Answer:
Your answer for both is 31 degrees
Step-by-step explanation:
Because they are similar we know their angles are the same. If you know the rule about triangles' interior angles always add up to 180, then you can just easily find this out.
First you do
82+67 = 149
Take that answer and minus it by 180
180-149 = 31

Hello there!
To find the zeros or the roots of a function, you just need to set the function equal to 0 then solve for x.
f(x) = (x + 4)² - 9
Set function equal to 0
(x + 4)² - 9 = 0
x² + 8x + 7 = 0
Now we can factor the left side
(x + 1)(x + 7) = 0
Then set factors equal to 0
x + 1 = 0 or x + 7 = 0
x = 0 - 1 or x = 0 - 7
x = -1 or x = -7
Thus,
The zeroes of the function are -1 and -7
