Question

Given m||n, find the value of x in the expression (5x-23) (7x-1).

A) x = 3
B) x = -3
C) x = 1
D) x = -1

Answer 1

The value of x for the missing angle in the diagram is: x = 17

How to find the missing angles?

Supplementary angles are two angles that add up to 180 degrees. When two angles are supplementary, they form a straight angle. They don't have to be adjacent to each other, but when they are put together, they form a straight line

These two angles in the diagram are supplementary angles and as such:

5x - 23 + 7x - 1 = 180

12x - 24 = 180

12x = 180 + 24

12x = 204

x = 17
