Answer:
1) x = 18 2) x = 7
Step-by-step explanation:
Edit: Decided to solve the second too! :)
1)
12/16 = x/(x+6)
12x + 72 = 16x
72 = 4x
x = 18
2)
(-4 + 4x)/64 = 27/72
-288 + 288x = 1,728
288x = 2,016
x = 7
Area of a triangle = 1/2 x base x height
Length of base = 15-5 = 10cm
Length of height = 15-5 = 10cm
1/2 x 10 x 10 = 50
So the area is 50cm^2
