Question

If tan a = 12/5 then find the value of (Sin A + Cos A) x Sec A

Answer 1

Answer:

Tan A = 12\5

Tan = P\B

P\B = 12\5

Let , P = 12k

B = 5k

H² = P² + B²

H² = (12k)² + (5k)²

H² = 144k² + 25k²

H² = 169k²

H = √169k²

H = 13k

Find : (Sin A + Cos A) x Sec A

(P\H + B\H) x H\B

(12k\13k + 5k\13k) x 13k\5k

17k\13k x 13k\5k

17k\5k

17\5 ( Ans )
