Vertical angles equal eachother
set angle 4 and angle 8 equal to eachother
3x=x+40
-x both sides
2x=40
÷2 both sides
x=20
solve for angle 4
3 (20)
60 B

6.95 to one decimal place would be 7 because if it was 6.9 then it would round to 7 and the 6.95 rounds the 9 to a 10 and you cant have 6.10 so it would be 7.
Answer: r = 7
Step-by-step explanation:
Subtract 12 from both sides to isolate the r variable. You have -42 = -6r. Divide both sides by -6 to get r by itself and you get r = 7. Verify by substituting 7 as the r value and solving the equation.
