Please helppp I have 40 mins to do Given the measure of angle 8, find the measure of angle 1.
(5 Points)
mz1= 50°
mz1 = 130
cannot be determined
mz1 = 40

measure of angle 1 is 130°.

step by step:

angle 8 = 50

angle 6 = 50 (because of vertical angles)

angle 4 = 50 (because fo alternate interior angles)

therefore, angle 1 = 130 (because of linear pairs)

angle 1 and angle 4 add up to 180°

step-by-step explanation:

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
