Question

यदि sinA = 3/2तो cos A का मान ज्ञात कीजिए।​

Answer 1

Answer:

The question is wrong

Step-by-step explanation:

SinA= perpendicular/Hypotenuse

And in a right angle triangle Hypotenuse is the longest side but as per your question the Hypotenuse is smaller than perpendicular.(3>2)

Answer 2

Answer:

√5/2

Step-by-step explanation:

sin A=3/2

in a right triangle ABC

AC=3(perpendicular

BC=2(hypotenious

AB=√5( by uding pythagores theoram

so cosA=B/H

hence

cosA=√5/2
