First we need to isolate the variable so we add 15 to both sides which is
w/4=43 then we need to multiply by 4 to both sides so its 4w=172
then divide by 4 which is 43 so the answer is w=43
Answer:
x = 36.5
Step-by-step explanation:
The two triangles are similar so we can use the similarity ratio to find x
AB ~ DE and BD ~ BA
15/31 = x/(x+39) cross multiply expressions
31x = 15x + 585
31x - 15x = 585
16x = 585 divide both sides by 16
x = 36.5 approximately
