Answer: 10,779 feets

Step-by-step explanation:

From the sketch attached ;

∠POT is the Angle of elevation = 33°

Height of tower = 7000 Feets

Taking the triangle POT

WHERE PT = 7000 Feets (Opposite)

Distance (d) between the bird and plane is the ADJACENT,

NOTE: (BP = OT = d)

Taking the tangent of the angle of elevation;

Tan Θ = opposite / Adjacent

Tan 33° = 7000 / d

Cross multiply

d × 0.6494075 = 7000

d = 7000 / 0.6494075

d = 10779.054 = 10,779 feets

Hajra's weekly pay this year is £676. This is 30% more than her weekly pay last year. Work out Hajra's weekly pay last year.

marissa [1.9K]

$\text{new pay}=\frac{130}{100}(\text{old pay})$ hence $\text{old pay}=\frac{130}{100}\cdot676=\boxed{\£520}$
