Answer:
equilateral triangle all angles add up to 180 and are equal so each angle is 60 degrees
angles on a line add up to 180.
angle CBD = 180-60 = 120
DBC is an isosceles triangle so it's base angles are the same.
180-120= 60
60/2=30
They are both 8 spaces away from 0 in opposite directions.
Answer:
Step-by-step explanation:
5(x + 5) < 85
5x + 25 < 85
5x < 85 - 25
5x < 60
x < 60/5
x < 12 <====
