M4 and m2 are equivalent
M2 and m3 are supplementary angles which mean they add up to 180°
M2+m3=180
Plug in the equation
3x+74+2x+11=180
Add up the x’s 3x+2x=5x
Add the constants on the left side
74+11=85
You get 5x+85=180
Subtract 85 from both sides
5x=95
Divide by 5
X=19
Now plug x into the m3 equation and get
2*19+11=49°
Because m4=m3, m4=49°
M3 and m1 are equivalent so set both equations equal to each other and solve bringing the same variables on each side
11x-9=7x+23
11x-7x=23+9
4x=32
X=8
Now plug x into either equation and you get
M3=79°
20+36= 56
56+20=76

Answer:
Step-by-step explanation:
price of tv and sales tax = 1.0688×$189 = $202.0032 ≅ $202.00
4 years = 3×365 days + 366 days = 1461 days
cost of electricity = 1461 days × $0.06/day = $87.66
lifetime cost = purchase price + electricity + repairs
= $202.00 + $87.66 + 2·$29
= $347.66
