On a piece of paper, use a protractor to construct a triangle with angle measures of 40° and 60º. What is the measure of the third angle?

80

Step-by-step explanation:

every triangle, no matter what shape or size, will have all angles add up to 180 degrees so 180-40-60=80

i dont know

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
