Answer:

y = 11

x = 8.6

Explanation:

The small triangle with 30,32,y looks like right triangle

so according to formula a^2 + b^2 = c^2

so 30^2 + y^2 = 32^2

900 + y^2 = 1024

y^2 = 124 => y = 11

The larger triangle also looks like a right triangle

so according to formula a^2 + b^2 = c^2

(30 + 10)^2 + 22^2 = (32 + x)^2

1600 + 44 = (32 + x)^2

so (x + 32)^2 = 1644

x + 32 = 40.55

x = 40.55 = 32 = 8.55 = 8.6
