Step-by-step explanation:
The angle shown is a right angle. Right angles have a total of 90°.
Therefore, I simply multiplied each answer by 4 because 4(x) = (answer).
A. 4 (14) = 56 + 42 = 98° ≠ 90° INCORRECT
C. 4 (10) = 40 + 42 = 82° ≠ 90° INCORRECT
B. 4 (16) = 64 + 42 = 106° ≠ 90° INCORRECT
D. 4 (12) = 48 + 42 = 90° = 90° CORRECT
An easier way to solve this problem is by simply just subtracting and dividing:
90 - 42 = 48
48 ÷ 4 = 12
