If tanA=815\frac{8}{15}158 then find sinA+cosA.
Question
If tanA=158 then find sinA+cosA.
A.
15/11
B.
7/17
C.
23/17
D.
8/11
Correct option is C
Given:
We are given that: tanA=158 We need to find the value of sin A + cos A .
Solution
Step 1: Using the Pythagorean identity to find sin A and cos A : Given tan A=158 , we can think of this as a right triangle where the opposite side is 8 and the adjacent side is 15. Using the Pythagorean theorem, we find the hypotenuse h :
