Answer:
∠x = 83°
Step-by-step explanation:
<u><em>Since ∠x and ∠y are supplementary ∠s so they add up to 180°</em></u>
So,
∠x + ∠y = 180
Where ∠y = 97°
∠x + 97° = 180
∠x = 180-97
x=83
97+x=180
therefore, the Correct choice is d) 15
the answer is C, because you solve 2.815-749, and after you divide the result per 4, so it is 1/4
