Hey There!

To find the height of the building there is only one way I can think of to find the answer;

Figure out the % 2.5 is out of 4 and apply that to 20...

2.5 is 62.5% of 4 and the tree is four meters tall.

20 is 62.5% of 32, so the building could be 32 meters tall

Hope I helped, Brainliest & Five stars is always appreciated.

What is the area of a sector that has a radius of 25 mm and has an angle measure of 50°?
Nimfa-mama [501]

The area of the sector is 86.81π mm²

<u>Explanation:</u>

Given:

Radius of the sector, 25mm

Angle, α = 50°

Area of the sector, A = ?

We know:

Area of the sector = \frac{\alpha }{360} X \pi r^2

On substituting the value, we get:

A = \frac{50}{360} X \pi X (25)^2\\\\A = 86.81 \pi mm^2

Therefore, the area of the sector is 86.81π mm²

The length of a rectangle is three times its width. If the perimeter is at most 128cm, what is the greatest possible value for t
anastassius [24]

Answer:

16 cm

Step-by-step explanation:

Let the width be x

The length will be 3 x since the length is three times the width

Perimeter=2(l+w) where l is length and w is width

By substituting 128 cm for perimeter, x for w and 3 x for l then

128=2(3x+x)

128=8x

x=\frac {128}{8}=16

Therefore, the width is 16 cm, the width is 16*3=48 cm
