Answer:
2 minutes
Step-by-step explanation:
As you can see, angle 5 and angle 6 are supplementary. And angle 5 and angle 3 are congruent because they are alternate interior angles.
So it will be
x+2 = 180- x+3
move x over from the right to the left
2x+2 = 183
move 2 over from the left to the right
2x = 181
divide by 2
x= 90.5
and angle 3 and angle 1 are vertical angles so they are congruent. Using the angle 3 formula to solve for the answer:
90.5+3 =93.5
When angles are congruent, their measures are congruent, therefore, measure of angle 1 is 93.5
Answer:
f^-1 (9) = 7 equals f = 9/7
Step-by-step explanation:
f^-1 x 9 = 7, f ≠ 0
1/f x 9 = 7
9/f = 7
9 = 7f
7f = 9
