Answer:

x = 8°

Explanation:

from the figure it is understood that the two angles 51 and 4x+7 form an angle of 90°, we can solve with a proportion

51 + 4x + 7 = 90

4x = 90 - 51 - 7

4x = 32

x = 32 : 4

x = 8

-------------------

check

51 + 4 x 8 + 7 = 90

90 = 90

same value the answer is good
