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
Step-by-step explanation:
well first try by addding the numbers and then dived it by 2
Answer:98
Step-by-step explanation:
We assume, that the number 200 is 100%.if 200 is 100%, so we can write it down as 200=100%.We also know, that x is 49% of the output value, so we can write it down as x=49%.Now we have two simple equations:
1) 200=100%
2) x=49%
we multiply both sides of the equation by x.then we divide both sides of the equation.
