Answer 1

the angles f and e sum to 90 since d = 90

then let e = x and t = 2x - 12

so the equation is

x + 2x - 12 = 90

3x - 12 = 90

solve for x to find the size of e

should be about 34

Answer 2

that equals 26?

Answer 3

when u solve for x right there

Answer 4

add 12 to both sides

3x = 102

divide 3

x = 34
