Write an equation that represents the line. Use exact numbers.

Answer:

∠1 and ∠5

Step-by-step explanation:

Angles 2, 3 and 4 are taking up 180 degrees because it is 1/2 of a circle. That means angles 1 and 5 are also taking up 180 degrees because both the angles add up to a straight line

Answer:

I hope you will understand my explanation

Step-by-step explanation:

Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees. Examples: 60° and 120° are supplementary angles.

Answer:

I think it's A.

Answer: ∠1 and ∠5

Step-by-step explanation:

You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.

Hope this helps :)

Answer:

 √90

Step-by-step explanation:

a² + b² = c²

3² + 9² = c²

9 + 81 = 90²

90 = c²

Answer:

B) [tex]x=\sqrt{90}[/tex]

Step-by-step explanation:

Pythagorean thm formula:

a² + b² = c²

Given:

a = 9

b = 3

c = x

Work:

a² + b² = c²

9² + 3² = x²

81 + 9 = x²

90 = x²

[tex]\sqrt{x^2} =\sqrt{90} \\x=\sqrt{90}[/tex]

Honestly, I'm not sure how to answer this, but I think this can help you.

Well if 5 and 2 fifths is one third of the total height of the building, then that means to find the total height of the building you need to times 5 2/5 by 3.

Answer:

We know the width maybe 22ft and at its widest.

IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.

With triangles;

The number of triangles is always 2 less than that that of its sides.

= 3 triangles + 2 = 5 sides.

The sum of interior angles

(n-2) x 180 = 540 degree

5-2 x 180

To determine the amount of sides; we remember

(n-2) 180

360 = (n-2) 180

+360 = 180 -360 +180

+360 = 180 = (3 triangles with 180)

900/180 = 5 sides.

If we say 5 triangles created with 3 given lengths

then same rule applies n-2 (180)

=7 sides

= if regular shape largest line 22 x 7 = 154 ft sq = Area.

Answer:

374

Step-by-step explanation:

First do the area of the triangle 7 x 22 = 308 308/2 = 154 22 x 10 = 220 220+154 =374

Answer:

[tex]54\:\mathrm{km/h}[/tex]

Step-by-step explanation:

Average speed is given by [tex]S=\frac{d}{t}[/tex], where [tex]d[/tex] is distance and [tex]t[/tex] is elapsed time.

Since we want the average speed of the entire trip, we need to total distance of the entire trip and the total time it takes for the entire trip.

What we know:

Substituting known values, we get:

[tex]S_{avg}=\frac{108\:\mathrm{km}}{2\:\mathrm{h}}=\boxed{54\:\mathrm{km/h}}[/tex]

Answer:

[tex]3x = 90 \\ x + y = 90 \\ x + y + z = 360[/tex]

55ft²

Answer:

Solution given:

the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2

=base area *2 laternal faces area

=25+2*15=25+30=55ft²

Answer:

RECTANGLE

Explanation:

Answer:

Rectangle

Step-by-step explanation:

If its sliced perpendicular from its circle base, that means its cutting vertically from it since perpendicular lines form a 90 degree angle.

Answer:

v = 628.32 m³

Step-by-step explanation:

v = πr²h/3

v = π(20/2)²(6)/3

v = π(100)(2)

v = 628.318530718

Rounded

v = 628.32 m³

Answer:

8 eggs.

Step-by-step explanation:

[tex]\frac{\frac{3}{4} }{1}(8)=\frac{6}{8}[/tex]

Therefore, if you use 6 cups of milk, you should use 8 eggs.

Answer:

6 or 8 is the answer you choose

Answer:

85 ft^2

Step-by-step explanation:

Ok, the square base area is 5 x 5 = 25 square feet

the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.

To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.

15 x 4 = 60 + 25 = 85 square feet

Let the number of visits equal x.

Multiply the number of points by the points per visit.

2.5x

Add that to the points he got for signing up:

2.5x + 35

This needs to equal the total points needed:

2.5x + 35 = 70

Solve for x:

Subtract 35 from both sides:

2.5x = 35

Divide both sides by 2.5:

X = 14

He needs 14 visits

Answer:

b = 42° and c = 180-42 = 138°

Answer:

b) 42°

c) 138°

Step-by-step explanation:

Get 42° by looking at its vertical partner(vertical angle). Get 138° by subtracting 42 from it. Subtract 42 from the sum of the entire angle, and get 180° degrees.

Hope this helps! Have a wonderful rest of your day!

angle one and angle three are vertical

Answer:

223.5 Km

Step-by-step explanation:

Area = Length x Width

Solving for Square Shape

8 · 6 = 48 km

Area = Length x Width

Solving for Rectangle Shape

9 · 14 = 126 km

Area = Length x Width ÷ 2

Solving for Triangle Shape

11 · 9 = 99 ÷ 2 = 49.5 Km

48 + 126 + 49.5 = 223.5 Km
