Yes - they have to be similar. Since they are using the same line as the hypotenuse, the ratio of the other two sides are in the same ratio (ie, the slope of the line), the 3 inner angles will be the same. Thus, the triangles will be similar.

now, with that template in mind, let's take a peek at yours

Help quick!!!! I’m stuck on this

irinina [24]

Answer:

A= pi r(r+h2+r2)

Step-by-step explanation:

Multiply the radius by pi, then set that aside for a bit.

Square the height and the radius as well, then add those together. This is how it would look:

3.14 x 4 = 12.56

7 x 7 = 49 ; 4 x 4 = 16 ; 16 + 49 + 4 = 69 ; 69 x 12.56

I think this is the answer. Can't say I'm 100% sure, though.
