Question

if m angle1=(4x+12), angle2= (7x+3), and m angle 3= 6y then x =? m angle 1=?, and m angle 2 =? and y =?? help!!!

Answer 1

drawn a picture if you can

Answer 2

Angles 1 and 2 will add up to 180 degrees if that is a straight line you drew.

So, 4x+12+7x+3=180
11x+15=180
11x = 165
x = 15

Answer 3

Then angles 2 and 3 will add up to 180 degrees.

So, first find out what angle two is by substituting 15 in for x.

7x+3=7(15)+3=105+3=108

Angle 2 + angle 3 = 180
108 + angle 3 = 180, so angle 3 must be 72 degrees

Answer 4

Angle 3 is 6y

6y = 72
y=72/6
y=12

Answer 5

ok thank you very much
