Question

if the sides are given in right angle triangle how to find its angle in a trigonometry chapter

Answer 1

Using any inverse trigonometric ratios.

In this case,

Hypotenuse= 5 cm

Opposite side = 3 cm

And Adjacent side = 4 cm

Now substitute these values in the trigonometric ratios

For Eg, let's take Sin

Sin ϴ = 3/5 => 0.6

ϴ= sin ^(-1) 0.6 (Using natural sine table find where 0.6 is)

We get ϴ = 36.86
