Step-by-step explanation:
Straight line = 180 °
5x + 78 = 180
5x = 180 - 78
5x = 102
x = 20.4
and y = 78 ° because y is an opposite angle of 78 °
Answer:
d
Step-by-step explanation:
add 18.4 on either side
Answer:
A = 22x + 330
from what I can see from the picture
Step-by-step explanation:
A = lw
A = (x + 15) x (22)
A = 22x + 330
Since we want to find f(2), we know that x=2.
We will then plug in x = 2 to our f(x)
We will then get
f(2) = 7^2 - 5 = 49 - 5 = 44
