Angle 1 and 2 are <u>supplementary</u> angles.
Answer:
C
Step-by-step explanation:
∠ AFD = ∠ AFB + ∠ BFC + ∠ CFD
The 3 angles form a straight angle and sum to 180°, that is
4x + 5 + 6x + 3 + 5x + 7 = 180, that is
15x + 15 = 180 ( subtract 15 from both sides )
15x = 165 ( divide both sides by 15 )
x = 11
∠ CFD = 5x + 7 = 5(11) + 7 = 55 + 7 = 62°, thus
∠ AFE = ∠ CFD = 62° ( vertical angles are congruent )

Answer:
f(x) = -x^2 + x + 13 find f(9) = -59
Hope this helps :)
look at the paterns. the 2 times always end in 2,4,6,8 or 0. if you know your three times table it would be easy for you to know your 6 just add 3 and do it again
