If the measure of angle 2 is 3x, and the measure of 1 is 5x - 12 what is the measure of angle 9 ?

Mariana [72]

3x+5x-12=180
8x=180+12
8x=192
x=192/8
x=24

angle 1 = 5x-12
=5(24)-12
=120-12
=108

angle 2= 3x =3*24=72

angle 1 = angle 9
angle 9= 108

Finger [1]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- 4x + 3y = 12 ( add 4x to both sides )

3y = 4x + 12 ( divide the terms by 3 )

y = $\frac{4}{3}$ x + 4 ← in slope- intercept form

with slope m = $\frac{4}{3}$ and y- intercept c = 4

---------------------------------------------------

Given

- 5x + 3y = - 9 ( add 5x to both sides )

3y = 5x - 9 ( divide the terms by 3 )

y = $\frac{5}{3}$ x - 3 ← in slope- intercept form

with slope m = $\frac{5}{3}$ and y- intercept c = - 3
