A) 8/40 = 1/5
b) 12/40 or 6/20
c) 26/40 or 13/20
Answer:
<h2>x = 28</h2>
Step-by-step explanation:
ΔARP and ΔCRD are similar. Therefore the sides are in proportion:
We have:
AR = 10 + x
CR = x
PR = 15 + 42 = 57
DR = 42
Substitute:
<em>cross multiply</em>
<em>use distributive property</em>
<em>subtract 42x from both sides</em>
<em>divide both sides by 15</em>
