Answer:
x = 2
z = 76°
Step-by-step 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
