Step-by-step explanation:
using trig, tangent is equal to opposite over adjacent.
in this case, the angle is 45, opposite is 7, and adjacent is a.
thus tan 45° = 7/a
solve for a to get a = 7/tan 45° = 4.32
Answer:
98
Step-by-step explanation:
So we have the expression:

And we want to evaluate it when x is 3 and y is 8.
So, substitute:

Multiply:

Add:

And we're done!
Since the opposite operation of addition is subtraction you subtract. So you add 14 both sides and now z is by itself. finally just add 2 and 14 which is 16
The information given requires you to rework the formula as :
distance÷time=rate
so then plug in values to get
5÷2=rate
and the answer will be 2.5 as your rate
