Answer:
<A = 76°
<B = 63°
<C = 41°
Plug in the value of x
<C = 34 + 7
<C = 41°
Step-by-step explanation:
(sum of ∆)
Solve for x
Add like terms
Subtract 78 from each side
Divide both sides by 3
x = 34
<A = 2x + 8
Plug in the value of x
<A = 2(34) + 8 = 76°
<B = 63°
<C = x + 7
Plug in the value of x
<C = 34 + 7
<C = 41°

Answer:
x=6
5x angle= 30 degrees
opposite angle=60 degrees
Step-by-step explanation:
the angle is a mirror of the right side, which is a 90 degree angle. so you take 90-54, which gets you 36. then you have 6x=36. so divide both sides by 6 and you get x=6. then substitute 6 for x.
5*6=30
6+54=60
