Question

Given the figure below, find the values of x and z.

Answer 1

x = 2

z = 76°

Explanation:

we know that angle 'z' plus 104 has to add up to 180° because they form a straight angle

therefore, ∡z = 76°

to find the measure of angle 'x', since it is a vertical angle with the 104° angle and vertical angles are equal then we can set up this equation:

13x + 78 = 104

13x = 26

x = 26/13

x = 2
