Answer:

The answer is 76.

Step-by-step explanation:

≅ means to be equal to.

☆Angle DGE ≅ EGF.

Therefore, 3x + 8 = 5x - 12

☆Let's solve that equation.

3x  + 8 = 5x - 12 \\  \frac{ - 5x \:  \:  \:  \:  \:  \:  \:   =  - 5x  \:  \:   \:  \:   \: \:  \:  \: }{ - 2x + 8 =  - 12}  \\  \frac{  \:  \:  \:  \:  \:  \:  \:  \: - 8  =  - 8}{  \frac{ - 2x}{ - 2}  =  \frac{ - 20}{ - 2} }   \\ x = 10

We found the value of x which is 10.

☆Let's Now plug in.

DGE \\ 3x + 8 \\ 3(10) + 8 \\ 30 + 8 \\ 38

and the other:

EGF \\ 5x - 12 \\ 5(10) - 12 \\ 50 - 12 \\ 38

☆They asked for what the angle of DGF measured. So we would have to add both sides

38 + 38 = 76

☆The answer is 76

Note that the right triangles with sides equal to 5, 12, 13 and 9, 12, 13 both have a side equal to 12. using this fact find the
kondor19780726 [428]
There is a mistake 9,12,13 is not a right triangle. but 9,12,15 is. IF you use this triangle instead, then the area of the 13,14,15 triangle is the sum of the area of the other two triangles.
