Question

if cos A= 12/13, then verify that sin A[1-tanA]=13/156

Answer 1

step by step explanation

Answer 2

Answer:your answer is 35/156

Step-by-step explanation:since by h^2=b^2+p^2 , the value of sinA is 5/13

Value of tanA is 5/12

so put these values on left hand side I.e

sinA[1-tanA]= 5/13[1-5/12]

=5/13[12-5/12]

=5/13[7/12]

=35/156
