Answer:

Angle 1: 40

Angle 2: 40

Step-by-step explanation:

A triangle's angles will ALWAYS add up to 180 degrees total, therefore you can subtract 100 from 180 to find what the measure of A and B are combined.

180 - 100 = 80

So now we know Angles A and B add to 80 degrees, but individually, each is half of that, so both are 40 degrees.

How do u find this??????????????????????/

The question is asking you to find the slope. Slope intercept form is writen:
y = mx + b    (m being the slope and b being the y-intercept)

The slope would be 5 and the y-intercept would be 0.

So, your answer would be y = 5x also known as C. y = 5x

Hope I helped! :)
