Answer:
x=36
Step-by-step explanation:
The 2 angles, ∠EAF and ∠FAB are on a straight line. This means they are supplementary, and add to 180 degrees.
So,
∠EAF +∠FAB =180
We know that ∠EAF is 3x and ∠FAB is 2x, so we can substitute them in
3x+2x=180
Combine like terms
5x=180
Divide by 5 on both sides
So, x=36 degrees, or the last choice
look at the photo..................
1.25 inches
2.5 x 4 = 10
11.25 - 10 = 1.25
69
to find f(3), we'll have to substitute x with 3
therefore,
f(3) = 19 × 3 + 12
= 57 + 12
= 69
Neither are correct, if you were to multiply a number by 0 it would be 0, meaning there would be no whole number.
Ex.) 24 * 0 = 0
