Answer:
x=21.5, plug it in and get 69 degrees
Step-by-step explanation:
4x-17+31=90
4x+14=90
4x=86
x=21.5
Answer:
68.54
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
for 1)
angle y = 180 - 110 = 70 degrees
angle z = angle y = 70 degrees
angle x = 89 degrees
for 2)
angle 1 = 180 - 85 = 95 degrees
angle 2= 180 - 95 - 85 degrees
angle 3 = 180-95 = 85 degrees
for 3)
m angle 3 = 25 degrees, same as m angle 1
