## Applications of Right Triangle Trigonometry Worksheet

Example of finding the length of a side.

To solve the above problem, you have to do the following steps.

Step 1. For triangle ABD, you already have AB=12, B=90 0 and D=60 0

So, tan 60 0 =opposite side/adjacent side

Since it is known from the trigonometry table that tan 60 0 =√3, you can write

Step 2 For triangle ABC, you already have AB=12, B=90 0 and C=30 0

So, tan 30 0 =opposite side/adjacent side

Since it is known from the trigonometry table that tan 30 0 =1/√3, you can write

## Basic Right Triangle Trigonometry Worksheets

So, cos x=adjacent side/hypotenuse

Now, as we know cos 60 0 =1/2, so , x=60 0

So, sin x=opposite side/hypotenuse

Now as sin 41.8 0 =0.666, so, x=41.8 0

## Practice Worksheet – Right Triangle Trigonometry

Sin 45 0 =opposite side/hypotenuse

Cos45 0 =adjacent side/hypotenuse

## Precalculus Right Triangle Trigonometry Worksheet

You know here Sin 30 0 =opposite side/hypotenuse

So, the swimmer travels 420 meter before he breaks the ocean surface.

## Right Triangle Trigonometry – Angle of Elevation and Depression Worksheet

From the above figure, it becomes apparent that tan x 0 =adjacent side /opposite side

Now as tan 66 0 =2.2,you have angle of elevation x= 66 0

Next, we know that the sum of all three angles of a triangle equals to 180 0

So, the remaining angle will be =180 0 –(66 0 + 90 0 ) = 180 0 – 156 0 =24 0

Hence, the angle of depression = 90 0 – 24 0 =66 0

cos x=adjacent side/hypotenuse

So, angle of elevation of the ladder= 60 0

## Special Right Triangle Trigonometry Worksheet

Let ABC is an equilateral triangle with sides x, y and z where x=y=z.

Next, as per the law of cosine, you know in the right-angle triangle ADC

cos C=adjacent side/hypotenuse

Now from the trigonometry table, you know that cos 60 0 =1/2

Similarly, as per the law of sine, you know that in the right-angle triangle ADC

Sin A=opposite side/hypotenuse

Now from the trigonometry table, you know that sin30 0 =1/2

Hence, you have in the right-angle triangle ACD, A=30 0 , C=60 0 , and D=90 0

Similarly, in the right-angle triangle ABD, A=30 0 , B=60 0 , and D=90 0
