Answer:

D=E (Base angle of isosceles triangle are equal)

D+E+F= 180° (sum of angles of a triangle️)

(4x+7)+(4x+7)+(5x+10) = 180

13x = 180- 24

x= 156/13 = 12°

so, E= 4x+7 = 4×12+7 = 55

Hope this helps:)

What is this answer???

Answer:

∠ ABC = 116°

Step-by-step explanation:

Since the angles are supplementary, they sum to 180° , that is

8x - 36 + 4x - 12 = 180

12x - 48 = 180 ( add 48 to both sides )

12x = 228 ( divide both sides by 12 )

x = 19

Then

∠ ABC = 8x - 36 = 8(19) - 36 = 152 - 36 = 116°
