Answer:
m∠A = 120°
m∠C = 45°
Step-by-step explanation:
all triangle angles add up to 180
(12x + 12) + 15 + (3x +18) = 180
15x + 45 = 180
15x = 135
x = 9
m∠A = (12x + 12) = 12(9) + 12 = 120
m∠C = (3x +18) = 3(9) + 18 = 45
Answer:
55
Step-by-step explanation:
D. 105
Alternate interior angles are congruent so angle A is congruent to angle B
The function that has an inverse that is also a function will have no repeated y-values. The appropriate choice is the third one.
{(-1, 3), (0, 4), (1, 14), (5, 6), (7, 2)}
Answer:
90m + 5
Step-by-step explanation:
Distribute 13 to (9-6m) and distribute 14 to (12m -8)
13*9 - 13*6m + 14*12m - 14*8 =
117 - 78m + 168m - 112 =
put like terms together
117-112 -78m + 168m =
5 + 90m
