There's 180 degrees in a triangle so and the two angles and then subtract by 180
Answer:
If you wanted to simplify the equation:
9y - 30 = 6
If you wanted to solve for y:
y = 4
Step-by-step explanation:
3(3y - 10) = 6
9y - 30 = 6
Add 30 to both sides of the equation:
9y - 30 + 30 = 6 + 30
Simplify:
9y = 6 + 30
9y = 36
Divide both sides of the equation by 9:
9y ÷ 9 = 36 ÷ 9
Cancel terms that are in both the numerator and denominator:
y = 36 ÷ 9
y = 4

Answer:
f(- 2) = 1
Step-by-step explanation:
Evaluate f(- 2) by substituting x = - 2 into f(x)
f(- 2) = - 2(- 2) - 3 = 4 - 3 = 1
