Question

given that cos A=5/13 and angle A is an acute angle find find the value of 2tan A+3 sinA

Answer 1

Hope it's helpful to you.

Answer 2

Step-by-step explanation:

cosA=5/13

so base=5,hypo=13

by using Pythagoras theorem,

H²= B²+ P²

P=√(169-25)

P = 12

sinA=12/13 and tanA= 12/5

putting values

=2*12/5+ 3* 12/13

=24/5+ 36/13

=492/65
