Step-by-step explanation:
Why is there a question mark?
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)

<u>Finding the constant of proportionality</u> :
<u>Finding y when x = 6</u> :
- y = 10(6)²
- y = 10(36)
- y = 360
The value of y is <u>360</u> when x = 6.
