Been waiting for half an hour pls help me

Stella [2.4K]

Answer:

13.7 cm

Step-by-step explanation:

there are 360° in a circle and in this image, we can see 90°+90°+66.4°=260.4
since we know that 360°-260.4°=99.6°
The angle measure of arc AD is 99.6°

Now that we covered that, we can use the arc length formula in order to find the length of arc AD.

arc length = 2πr(Θ/360°)
2π(7.9)(99.6°/360°) = 13.7329
rounded to the nearest tenth = 13.7

If the sides of two similar triangles are in the ratio of 3:5, find the ratio of their areas.

Kazeer [188]

Ratio of areas of similar triangles is 9 : 25.

Solution:

Given data:

Ratio of sides of two similar triangles = 3 : 5

To find the ratio of areas of the triangles:

We know that,

<em>In two triangles are similar, then the ratio of their area is equal to the square of the ratio of their sides.</em>

$$\text{Ratio of areas} = \frac{\text{Area of triangle 1}}{\text{Area of triangle 2} }$

$$=\left(\frac{3}{5}\right) ^2$

$$=\frac{9}{25}$

Ratio of areas of similar triangles is 9 : 25.
