Answer:
92∘
Step-by-step explanation:
Supplementary angles combine to create a straight angle. So, they have a sum of 180.
∠x + ∠y
∠x + 88 --------------> 180
=92∘

<h2><u>
Answer:</u></h2>
y = cos ^- 1 (x)
Step-by-step explanation:
The Function y = cos -1x = arccos x and its Graph: Since y = cos -1x is the inverse of the function y = cos x, the function y = cos -1x if and only if cos y = x. This leaves the range of the restricted function unchanged as [-1, 1].
