Let smaller angle be x
Let larger angle be 20 + x
Sum of two supplementary angles = 180°
x + 20+ x = 180°
2x + 20 = 180
2x = 180-20 = 160
x = 160/2 = 80
Smaller angle = x = 80°
Larger angle = 20 + x = 20 + 80 = 100°
I hope it is helpful:D
Answer:

Step-by-step explanation:
If -2 and 5 are double roots of the polynomial function, then the function expression is

Rewrite this function in standard form:

The constant term of the polynomial in standard form is -40, so

Therefore, the function expression is

Answer:
Step-by-step explanation:
(x-3)² - 7 = (5-3)²-7
= 2²-7
= 4 - 7
= -3
Divide -4 on both sides then change the greater then sign to less then so it looks like....-x < -3
