Answer:
What are you supposed to do
Step-by-step explanation:
Answer: 155°
because ∠a and ∠c are 2 opposing angles => m∠a = m∠c = 155°
for just the slope its 3/5 or in decimal its .6
y's on top x's on bottom
1--2
1+2=3
2--3
2+3=5
so slope is 3/5 or .6
b . 4/5
60 :15 minute : 4
3 /15 x 4 = 12/15 = 4/5
