Sina - (cosa)(tanb)/cosa + (sina)(tanb)
sina ≡ (tana)(cosa)
(tana)(cosa) - (cosa)(tanb)/cosa + (tana)(cosa)(tanb)
= cosa(tana - tanb)/cosa(1 + tanatanb)
(cosas cancel out)
= (tana - tanb)/(1 + tanatanb) ≡ tan(a-b)
Answer:
Step-by-step explanation:
A proportional constant satisfies
y/x=k, where k is the constant of proportion
Since
y/x=k
y=kx
You are given
y=1.5x so
k=1.5
Answer: 1
Explanation: Doing -50+51 is essentially the same as 51-50
The volume of the triangular prism is the Area of the base times the height
the area of the base is:

and the volume is:

now b=10 yards, a=20 yards, and V=600 yards^3
we clean the height

the answer is height = 6 yards
