Explanation:
5. θ = 60°
→ To find the value of y ,
Cos θ = b/h
putting the values in terms of cos
Cos 60° = y/16
1/2 = y/16
16/2 = y
y = 8 unit
→ To find the value of x ,
Sinθ = P/h
putting the values in terms of sin
Sin60° = x/16
√3/2 = x/16
16×√3/2 = x
16×1.73/2 13.84 unit
6. θ = 30°
→ To find the value of y
tanθ = p/b
putting the values in terms of tan
tan 30° = 2/y
1/√3 = 2/y
2×√3 = y
3.46 unit = y
→ To find the value of x
Sin θ = p/h
putting the values in terms of sin
Sin 30° = 2/x
1/2 = 2/x
4 unit = x
