The measure of the vertex angle of an isosceles triangle is one-fourth
that of a base angle.
(i also need the equation)

measure of each base angle =

measure of vertex angle =

measure of each base angle =  80 each angle

measure of vertex angle = 20

Step-by-step explanation:

x=base angle    

2x+ x/4= 180

Multiply everything by 4 to eliminate the fraction

8x+x = 720

9x=720

x=80

80/4=12

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
