Question

if angle A=60° then find the value of (cosA +secA/cosecA+tanA)​

Answer 1

Step-by-step explanation:

If secA+tanA = 2, then what is the value of sinA+cosA?

Looking for the right CA guidance? Look no further.

Given that secA+tanA=2(1)

You know,

⇒sec2A−tan2A=1

⇒(secA+tanA)(secA−tanA)=1

⇒2(secA−tanA)=1

⇒secA−tanA=0.5(2)

Now we can add equation 1 and 2 and we will get, 2secA=2.5⇒cosA=22.5=2025=45

So you can find from the above result that sinA=35

Thus

SinA+CosA=45+35=75=1.4 ■

From this I can predict one more thing that the angle A is 37° and the sides of the triangle is in a Pythagorean triplet (3,4,5).

Don't be confused from the last line,it is external.
