Answer:

<B = 110°

Explanation:

The interior angles formed by the sides of pentagon sum up to 540°.

So <A + <B + <C + <D + <E = 540°

130° + (x - 5)° + (x + 30)° + 75° + (x - 35)° = 540°

3x + 130 + 30 + 75 - 5 - 35 = 540

3x + 195 = 540

3x = 345

x = 115°

<A = 130°

<B = x - 5 = 115 - 5 = 110°

<C = x + 30 = 115 +30 = 145°

<D = 75°

<E = x - 35 = 115 - 35 = 80°

Hope it helps......
