Question

Ina triangle ABC right angled at C, if tan A = 1, find the value of Sin A Cos B + Cos A Sin B​

Answer 1

Answer:

9. In triangle ABC, right-angled at B, if tan A = 1/ 3, find the value of: (i) sin ...

Answer 2

Solution:-

tanA=31

ACBC=31

AC=3BC

Also, (AC)2+(BC)2=(AB)2

3(BC)2+(BC)2=(AB)2

AB=2BC

AB:BC:AC=2:1:3

sinA=ABBC=21 cosA=ABAC=23

sinB=ABAC=23
