Sonbull [250]

Answer:

Answer 44

Step-by-step explanation:

I'll do some of it. You can supply some of the vocabulary.

<Q = 56 degrees                         The triangle is isosceles.

<PRQ = 180 - 56 - 56                    All triangles have 180 degrees.

<PRQ = 68                                     Do the subtraction

<PRQ = <SRT                                 Why is this so? You have the term.

<TRS = 68 degrees                        The reason is the same as the last part.

<T = <RST                                         The triangle is isosceles (2 equal angles)  

<T = 68                                             Two equal angles = the same degrees    

S = 180 - <T - < RST                         S is the left over from the 2 equal angles.

S = 180 - 68 + 68                             Substitute.

S = 44

Vladimir [108]
You know that you have 20 inches to start with, then it will grow 2h four times, or 8h total. Then it will grow h 2 times or 2h. You add the 20, 8h, and 2h, to get 20+10h.
