Answer:
Step-by-step explanation:
x - an angle
x - 150° - the angle's suplementary angle
Measure of suplementery angles adds to 180°
x + x - 150° = 180°
2x = 180° + 150°
2x = 330°
x = 330°÷2
x = 165°
x-150° = 165° = 150° = 15°
1260
He asked 180 people and 63 said cookies so I think you have to do 63 out of each 180 people so you would do 3600 ÷ 180 = 20, 20 x 63 =1260
