Complementary angles add up to 90 degrees. We know that AXB is 20 degrees, and AXB is complementary to CYD and FZE. So CYD and FZE are 90-20, so each angle is 70 degrees
CYD = 70 degrees
FZE = 70 degrees
CYD + FZE = 70 + 70 = 140

Answer:
Step-by-step explanation:
Given
Required
Write an explicit formula
Let n = 1
Let n = 2
Let n =3
Let n = 4
So, we have:
Following the above pattern:
Open bracket
Answer:
Step-by-step explanation:
f(x) = x^2 + 5
g(x^2 + 5) = (x^2 + 5)^2= x^4 + 5x^2 + 5x^2 + 25 = x^4 + 10x^2 + 25
h(x^4 + 10x^2 + 25)= -2(x^4 + 10x^2 + 25)
-2x^4 - 20x^2 - 50
