Answer:
a=34 °
b=76°
c=70°
d=70°
Step-by-step explanation:
The angles 76° , 34°, and c make up a triangle. A triangle has a sum of 180°.
180° = 76° + 34° +c
c=70°
The parallel lines create 2 congruent triangles so we can use the same angles from the first triangle for the second one.

I'm sorry, I don't know if I know this but you should try Desmos if you haven't already. It's great for helping with slopes and stuff like this
Answer: (A) 10
<u>Step-by-step explanation:</u>
<u>Value</u> <u>Quantity</u> = <u>TOTAL Value</u>
dimes: .10 Q + 5 = .10(Q = 5)
quarters: .25 Q = .25Q
Dimes + Quarters = $4.00
.10(Q + 5) + .25Q = 4.00
.10Q + .50 + .25Q = 4.00
.50 + .35Q = 4.00
.35Q = 3.50
Q = 10
Quarters = 10
Dimes = Q + 5
= 10 + 5
= 15
