What is side Bc round to nearest hundredth
neonofarm [45]

Answer:

BC = 15.01

Step-by-step explanation:

Solve this question using a trigonometry ratio, which you can remember them all with SohCahToa, which says:

sinθ = opp / hyp

cosθ = adj / hyp

tanθ = opp / adj

θ means the "angle of reference" (angle we are talking about).

In this problem, θ is A = 65°,

To decide which trig. ratio to use, find out which sides we want to use. We will use AC = 7 because we know it.

We also use BC because we need to find it.

In relation to ∠A or θ, <u>AC is adjacent</u> and <u>BC is opposite</u>.

The ratio with adjacent and opposite is tangent.

tanθ = opp / adj              Substitute the variables for this question

tanA = BC / AC               Substitute the values you know

tan65° = BC / 7               Rearrange this and isolate C

BC = 7tan65°                  Multiply 7 and tan65 to find the missing side

BC = 15.011548......          Exact answer on your calculator

BC ≈ 15.01                       Round to nearest hundredth

Sariya and Kate went to lunch and their total bill was $36.96. If they
sasho [114]

Answer:

$ 44.352

Step-by-step explanation:

The bill of both of them was $36.96. And they gave a tip of 20%. So , the total amount paid will be ,

=> Amount = Bill + 20% of Bill

=> Amount = $36.96 + 20% of $ 36.96

=> Amount = $36.96 + 1/5 * $36.96

=> Amount = $36.96 + $7.392

=> Amount = $ 44.352

<h3><u>Hence</u><u> the</u><u> </u><u>amount</u><u> </u><u>paid </u><u>by </u><u>them </u><u>is </u><u>$</u><u>4</u><u>4</u><u>.</u><u>3</u><u>5</u><u>2</u><u>. </u></h3>
