Answer:1=70 2=65 3=95
Step-by-step explanation:
Angles in a triangle add up to 180°
180-45=135-65=70
1=70°
Angles on a straight line add up to 180°
180-45=135-70=65
2=65°
Angles in a triangle add up to 180°
180-65=115-20=95
3=95°
<h3>
Answer: E. 45/4</h3>
===========================================
Work Shown:
Because we have similar triangles, we can form the proportion below to isolate x.
(AC)/(BC) = (CD)/(AC)
(15)/(20) = (x)/(15)
15*15 = 20x .... cross multiply
225 = 20x
20x = 225
x = 225/20
x = (5*45)/(5*4)
x = 45/4
