Question

If 5sinA – 4 = 0, find the value of 3tanA + 5cosA.
step by step answer

Answer 1

Answer:

7

Step-by-step explanation:

5sinA-4=0

sinA=4/5 (sin=p/h)

now find base

by pythagoras theorem

h^2=p^2+b^2

25=16+b^2

b=3

now, ATQ

3tanA +5cosA

put the value of tanA and cosA

3×4/3+5×3/5

4+3

=7
