Please help and explain it ty

<B = 110

Step-by-step explanation:

<A + <B + <C+ <D + <E = 540

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

Combine like terms

3x+195 = 540

Subtract 195 from each side

3x+195-195 = 540 -195

3x =345

Divide each side by 3

3x/3 = 345/3

x =115

We want to find angle B

B = x-5

    115-5

<B = 110

m∠B = 110°

Step-by-step explanation:

It tells you that all the terms inside the shape equals to 540.

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

Combine like terms:

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

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

Combine like terms... again:

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

3x+195=540

Now, you subtract the 195 from 540 so that the variable is alone on one side. 540 - 195 = 345

3x=345

To find the value of x, you have to divide:

345/3x = 115

But, since it asks for angle B, we have to plug in 115 in the value of x to get the degree:

m∠B = (x-5)

m∠B = ((115)-5)

m∠B = 110

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
