Answer:
8. ∠1=118° ∠2=118°
9. ∠1=72° ∠2=108°
10. ∠1=127° ∠2=127°
Step-by-step explanation:
8. In this problem, 118° is corresponding to ∠1, meaning they are congruent. ∠2 is supplementary with ∠1, meaning that together, they equal 180°. So, to get ∠2, you must subtract 118° from 180°
9. In this problem, 72° is same side interior with ∠1, meaning they are congruent. ∠2 is supplementary with ∠1, so you do 180°-72°= 108°
10. In this problem, ∠1 is vertical angles with 127°, making them equal to each other. ∠2 is corresponding with 127°, making them also equal.

Answer:
y= -10x + 30
Step-by-step explanation:

The x-intercept of a quadratic function is the x-value of the function (if there is any) that has a y-coordinate of zero. Hence, you can solve for the roots of this function and if you're using a graphing calculator, you may graph this function to find the roots that intercepts the x-axis. You could also just substitute 0 for f(x), since f(x)=y and that'd be the equivalent of having a y-coordinate of zero to find the x-intercept.
15:24
divide both sides by 3
b. 5:8
for 6:30
divide both sides by 6
1:5
