In mathematics, an inverse function<span> is a </span>function<span> that "reverses" another </span><span>function. To understand clearly the given expression, we write it as follows:
y = (x + 5) / 7
The inverse would be as follows:
</span>
y = (x + 5) / 7
x = 7y -5
f^-1(y) = 7x -5 <--------- LAST OPTION

Answer: a = 45°
Step-by-step explanation:
The measure of∠PSR is given: 90°
Given PS = RS, this is an isosceles triangle. so measure of ∠SPR, labeled "a" is equal to the measure of ∠SPR.
The total of all angles in a triangle is 180. So subtract 90, then divide by 2.
180-90 = 90
90/2 = 45
a = 45°
<em>If "b" is supposed to be the measure of ∠SRQ, that is 15° The larger triangle is equilateral; all the angles are 60°. 60 - 45 = 15</em>
Okay so the answer is the fist multiple choice
