Answer:
3
Step-by-step explanation:
First make an inequality to solve for x
(x + 45) + [(x + 45) - 30] + [2x + (x + 45)] = 180
x = 15
now plug x back into each equation and solve
first angle = 60°
second angle = 30°
third angle = 90°
Answer:
Step-by-step explanation:
To find the slope you look at how much the line rises after going 1 unit to the right. In this equation it rises 2 after going over, or running, 1 unit to the right. So the rise over run is 2 over 1. It can be represented in a fraction 2/1. The slope is the rise over run, being 2.
The constant in the equation, or the y-intercept, is the point where the line intersects the y axis, the dark vertical line. You can count how many units it is from the origin where the 2 black lines intersect. The y-intercept in this is 2.
The slope is the number bedfore the x and the y intervept is the constant after the x.
The answer is 6 because 4+1=5+1=6
