Since opposite angles in a trapezoid are supplementary (add to 180) we can say that :
x + 2x =180
3x = 180
x=60
So, angle A = 120 ° and angle C = 60°
What do we do with the 12? Multiply, divide, subtract or add
Answer: (a.) -19 (b.) 78
Step-by-step explanation:
(a.) -33+14= -19 (b.) 75 - x = 78
(b.) 75 to zero = 75 Zero to -3
is 3 points behind zero, this make more distance from 75 so…
(b.) 75+3 = 78
It is A maybe use your calculator
