Answer:
(a, b, c, d) = (101°, 79°, 83°, 97°)
Step-by-step explanation:
∠a is the supplement of the one marked 79°, so is ...
∠a = 180° -79°
∠a = 101°
__
∠b is a corresponding angle to the one marked 79°, so is congruent to it.
∠b = 79°
__
∠c is a vertical angle with the one marked 83°, so is congruent to it.
∠c = 83°
__
∠d is a same-side interior angle between two parallel lines, so is supplementary to ∠c.
∠d = 180° -83°
∠d = 97°
C. F(x)=4x2-2x+16 .....:...
7 hrs per week on internet
9 hrs per week playing video games
thats a total of 16 hrs a week
5 hrs free time per day......thats (5 * 7) = 35 hrs free time per week
16/35 = 0.457 = 45.7% <==
