Answer: 2.077x10^-4
Step-by-step explanation:
angle 1+ angle 2=180 supplementary angles add up to 180
angle 2=x assign angle a variable
angle 1= 3x-38 find equation for first angle
3x+x-38=180 set both angles added together equal to 180
4x-38=180 combine like terms
4x=218 add 38 to both sides
x=54.5 divide by 4
angle 2= 54.5
angle 2= (3x54.5)-38 plug back in and solve
angle 1= 125.5
3c + b.....when c = -7 and b = 4
3(-7) + 4 =
-21 + 4 =
- 17 <===
