width height hypotenuse angle Right Angled Triangle

35° width height hypotenuse

Graph 1 Plot your angle against the value of HEIGHT ÷ HYPOTENUSE Angle Height ÷ Hypotenuse

Graph 1 Plot your angle against the value of HEIGHT ÷ HYPOTENUSE Angle Height ÷ Hypotenuse

Graph 2 Plot your angle against the value of WIDTH ÷ HYPOTENUSE Angle Width ÷ Hypotenuse

Graph 3 Plot your angle against the value of HEIGHT ÷ WIDTH Angle Height ÷ Width

Graph 1 Plot your angle against the value of HEIGHT ÷ HYPOTENUSE Angle Height ÷ Hypotenuse

Graph 2 Plot your angle against the value of WIDTH ÷ HYPOTENUSE Angle Width ÷ Hypotenuse

Graph 3 Plot your angle against the value of HEIGHT ÷ WIDTH Angle Height ÷ Width

The relationship between the sides of a right angled triangle and the angle is predictable

60° 10 cm 20 cm hypotenuse width Width ÷ Hypotenuse = ÷ 20 = 0.5

35° 10 cm 7 cm height width Height ÷ Width = 0.7 ? ÷ 10 = 0.7 ? = 7

A Guide To Finding A Missing Side Step by Step Guide Which two sides are involved? Height, Width or Hypotenuse? Use the correct graph to look up the value for the angle. Write the sum out using the two sides and the value from the graph. Now work out the unknown side. An example 12 cm 30° ? Width & Hypotenuse 0.87 Width ÷ Hypotenuse = 0.87 ? ÷ 12 = 0.87 ? = 10.44

A Guide To Finding An Angle Step by Step Guide Which two sides are involved? Height, Width or Hypotenuse? Find the correct graph. Perform the calculation for the graph. Look up the value on the graph, and read off the correct angle. An example 6 cm ?° 13 cm Height & Width Height ÷ Width ? = 25° = 6 ÷ 13 =

How far above the houses will the aircraft pass? The runway is 4.5km long in total. The acceleration stage is 3.5km. The take off angle is 10°. The housing estate is 7.5km from the end of the runway. Acceleration stage Take-off End of runway The diagram is not drawn to scale. Take-off angle

How far above the houses will the aircraft pass? The runway is 4.5km long in total. The acceleration stage is 3.5km. The take off angle is 10°. The housing estate is 7.5km from the end of the runway. 3.5 km Take-off End of runway The diagram is not drawn to scale. Take-off angle 1 km 7.5 km 10°

How far above the houses will the aircraft pass? The diagram is not drawn to scale. 1 km 7.5 km 10° 8.5 km ? Height ÷ Width =0.18 ? ÷ 8.5 = 0.18 ? = 1.53 Roughly 1.5km above.

The tower is 72 metres tall. Angle of rope The angle of the rope is 25°. How long should the piece of rope be? A piece of rope is attached to the top of a tower and the ground several metres away. How far away is the rope fixed from the tower? The diagram is not drawn to scale. Rope Tower
