(1- cos2x) dx
= x - 1/2 sin2x + c
= x - 1/2 ( 2*sinx cosx) +c
= x - ((sinx) (cosx)) +c
Answer:
ABC = 87°
Step-by-step explanation:
So ABC is x + 32 because the angles are vertical. ABC is also supplementary to ABD so you can make an equation.
3x + 15 = 180
3x = 165
x = 55
ABC = 55 + 32 = 87
Ben=x
Amy=x-24
x-24/x = 3/5
5x-120 = 3x
5x-3x = 120
2x=120
X= 60
Ben = 60
Amy = 60-24 = 36
