Ответ:
The answer is 75
Step-by-step explanation:
All you need to do since angle C and F are congruent/same is make an equation with those numbers and solve for x
2.5x + 8 = 3.5x - 7
subtract 8 from both sides
2.5x = 3.5x - 15
subtract 3.5 from both sides
-x = 15
multiply both sides by -1
x = 15
Since angles A and D are both 90. And angles C and F are both 15. You add them to make 105.
Subtract 180-105 to get 75
