Using the sine ratio in the right triangle
sin15° = =
( multiply both sides by x )
x × sin15° = 16 ( divide both sides by sin15° )
x = ≈ 61.8 ( to the nearest tenth )
The solution is x=1 and y=-2
Further explanation:
Given equations are:
Multiplying equation no. 1 with 2 will give us:
Eqn 3
From equation no 2:
Putting the value of y in eqn 3
The solution is x=1 and y=-2
