Your answer, in your set notation, is
{-2, 7}
the answer would be4.7^-10^4
It would be C because if you plug all the x-values in to the equation, it would get the same y values, which would satisfy the equation.
Answer:
The angle of A is 80°
Step-by-step explanation:
Given that angle A lies on a straight line which is 180°. So in order to find A, you have to substract 100° from 180° :
∠A + 100° = 180°
∠A = 180° - 100°
∠A = 80°
