Question

if sin =5 by 13 find cos A​

Answer 1

Answer:

the value of cos A is 12 by 13

Answer 2

Step-by-step explanation:

Given,

Sin =5/13

Sin = Lamb/Karn

CosA = aadhar/Karn

aadhar = √karn^2-lamb^2

aadhaar = √13^2-5^2

aadhar = √169-25

aadhar = √144

adhaar = 12

Cos A = aadhar/Karn

Cos A = 12/13
