F(x)= -x2 + 1 for x =-3

f(-3) = -8

Step-by-step explanation:

It is given that f(x) = - x² + 1. Find the value of f(x) by substituting x = -3 into f(x)

f(x) = - x² + 1

f(-3) = -(-3)² + 1

= -9 + 1

= -8

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
