Answer: cos²(θ) + sin(θ)sin(e)

Step-by-step explanation:

sin (90° - θ)cos(Ф) - sin(180° + θ) sin(e)

Note the following identities:

sin (90° - θ) = cos(x)

sin (180° + θ) = -sin(x)

Substitute those identities into the expression:

cos(x)cos(x) - -sin(x)sin(e)

= cos²(x) + sin(x)sin(e)

Joe spent $4.36 for gasoline in driving 68 miles. How much would he spend in driving 85 miles?

monitta

He will spend $5.45 if he is driving 85 miles.

4.36/68=0.064
That means every mile he drives he spends on average 6 cents.
Now 0.064 * 85 equals $5.45.
