The answer is 9.5 ( rounded, answer is 9.486833)
The sum total of the angles in a triangle is equal to 180° degrees.
X and Z equal 72
Y equals 108.
This is because y and 108° are vertex angles meaning they are both equal to each other. X is 72 because it’s form a supplementary angle with 108°. So what I did to find x is I subtracted 108 from 180 to get 72°. Then I know x and z are vertex angles meaning that z is also equal to 72°
Answer:
y = -x + 8
Remember that the slope-intercept form had formula y = mx + b where m is the slope and b is the y-intercept.
