Question

If 5 tan=4 find the value of 5 sin - 3 cos/5sin 2Cos

Answer 1

the value of 5 sin - 3cos/5sin2cos=41/40root41

Answer 2

Answer:1/6

Step-by-step explanation:

Tan@=4/5=perpendicular/ base

Hypotenuse=?

(Hypotenuse) ²=(perpendicular) ² + (base)²

(H)²=(4)²+(5)²

(H)²=16+25

(H)²=41

H=√41

5sin@-3cos@/ 5sin@+2cos@

(5×4/√41)-(3×5/√41) / (5×4/√41)+(2×5/√41)

(20/√41)-(15/√41) / (20/√41)+(10/√41)

(20-15/√41) / (20+10/√41)

(5/√41) / (30/√41)

5/√41×√41/30

1/6
