A + b + c = 180
a = 2b
b = c + 4
Substitute the b equation into the a equation
a = 2(c + 4)
a = 2c + 8
Substitute equations a and b into the first equation
2c + 8 + c + 4 + c = 180
4c = 168
c = 42
Find the other angles using c
b = 42 + 4
b = 46
a = 2(42) + 8
a = 92
Therefore angle a is 92 degrees, angle b is 46 degrees, and angle c is 42 degrees.

Answer:
Step-by-step explanation:
Bonsoir,
63°
(rs)(4)=(2rootX)(rootX)
(rs)(4)=2x
(rs)(4)=8
(r/s)(3)=(2rootX)/(rootX)
(r/s)(3)=2
.1 = 1/10
.16_6 = 1/6
0.6_6 = 2/3
0.6 = 3/5
