In ABC,if sin A=4/5 and tan A =4/3,then what is cosA?

Answer:

Cos A = 3/5

Step-by-step explanation:

Step 1: define the functions

Sine A= Opp/Hyp

sin A=4/5

I.e. Opp = 4,; Hyp = 5

tan A =4/3

Tangent A= Opp/Adj

I.e. Opp = 4,; Adj= 3

Step 2. Define Cosine and solve for Cos A.

Cosine A = Adj/Hyp

From the Above substitute the given sides

I.e. adj= 3; Hyp = 5

Therefore

Cos A = 3/5

Company A had a loss of $255 in January. Company B had a profit of $162 in January. What was the difference between the profits
Julli [10]

Answer:

The difference of the profit of two companies is $ 417

Step-by-step explanation:

Given as :

The company A loss amount in January = $ 255

The company B profit amount in January = $ 162

Let the difference between there profits = x

So, x = company B profit - ( company A profit)

I.e x = company B profit - ( - company A loss)

Or, x = $ 255 + $162

∴   x = $ 417

Hence The difference of the profit of two companies is $ 417  . Answer
