Answer:

Answer z = 55

Explanation:

Remark

I think you have to assume that the horizontal line is a straight line. If that is so, the other line, the one that looks like it is going up and to the left, cuts that horizontal line in such a way that the angles are supplementary. Supplementary angles are angles that add up to 180 degrees.

Equation

2z - 10 + 80 = 180 Combine the like terms on the left.

Solution

2z + 70 = 180 Subtract 70 from both sides.

2z + 70 - 70 = 180 - 70 Combine

2z = 110 Divide by 2

2z/2 = 110/2 Do the division

z = 55 Answer

Answer:

z=55

Explanation:

The two angles form a straight line which is 180 degrees

80 + 2z-10 = 180

Combine line terms

70 +2z = 180

Subtract 70 from each side

70-70 +2z= 180 -70

2z = 110

Divide by 2

2z/2 = 110/2

z = 55
