Answer:

D. 15/8

Step-by-step explanation:

In the diagram above, using trig ratio;

SOH CAH TOA

sinФ = opposite / hypotenuse

cosФ = adjacent / hypotenuse

tanФ = opposite / adjacent

But you need to know how to identify all the side;

In this case, since our major concern is angle A, that is; since we are to find tan of angle A, then this makes AC to become our adjacent, BC to be our opposite and AC will always be the hypotenuse regardless of whether we are to solve for angle A or angle B. But of course, if we are to solve for angle A the adjacent will not be AC anymore, it will definitely change.

But since we are solving for angle A;

adjacent = AC =8

opposite = BC = 15

Applying our trig. formula;

tanФ = opposite / adjacent

tan A = 15/8

Tangent(Angle) = Opposite / adjacent

Tangent(A) = 15 / 8

The answer is D. 15/8

Train revived a raise of $80 per week. If he was making $500 per week before the raise, what is the percent change in his earnin

kotegsom [21]

Answer:

Train got a raise of 16%

Step-by-step explanation:

To find this, start by taking the equation for percent change

(New - Old)/Old * 100 = % Change

Now plug in known values

(580 - 500)/(500) * 100 = % change

80/500 * 100 = % change

.16 * 100 = % change

16 = % change

Mila [183]

550,000 or 600,000

780,573 estimates to 780,000 or 800,000
229,615 estimates to 230,000 or 200,000
780,000-230,000=550,000
or
800,000-200,000=600,000
