Sin x = opp/hyp
cos x = adj/hyp
tan x = opp/adj

sin A = 40/50 = 4/5
cos A = 30/50 = 3/5
tan A = 40/30 = 4/3

sin C = 30/50 = 3/5
cos C = 40/50 = 4/5
tan C = 30/40 = 3/4

Solve 18n - 7p-15n = 5p for n.<br> A n = 1<br> B. n=2p<br> C. n = 1/2<br> D. n=4p
andrey2020 [161]

Answer:

<h3>The answer is option D</h3>

Step-by-step explanation:

18n - 7p-15n = 5p

To solve for n first make n the subject

Group like terms

That's

18n - 15n = 5p + 7p

Simplify

3n = 12p

Divide both sides by 3 to make n stand alone

That's

3n/3 = 12p/3

We have the final answer as

<h2>n = 4p</h2>

Hope this helps you
