100 points! Can someone he|p me with geometry and exp|ain how to do it, p|ease?
*SPAM ANSWERS WILL NOT BE TOLERATED*

Answer:
A = 45 degrees
Step-by-step explanation:
PS AND PQ IS THE SAME,
which means that each side is the same,(left and right)
a triangle, has 180 degrees
180-90
=90
90/2(get the angle of each sides that are left)
=45 degrees is the answer
Now pay up 100 points, lol
Answer:
The measure of angle a is 45 degrees.
Step-by-step explanation:
Notice that since PS = RS, this is an isosceles triangle. This means that the base angles are equal. We also know that the sum of interior triangles of a triangle equals 180, then, if 'a' is the base angle, we have the following equation:
90 + a + a = 180
2a = 180 - 90 = 90
a = 90/2 = 45
a = 45
