Question

The diagram shows a right-angled triangle.

a
12 cm
24 cm
Find the size of angle x.

Answer 1

Given that , Length of Base and Hypotenuse is 12 cm and 24 cm , respectively .

Need To Find : The measure of Angle x .

As We know that ,

Cos ∅ = Base / Hypotenuse

ㅤㅤ By Substituting known Values :

ㅤ⤀Cos x = 12/24

ㅤ⤀Cos x = ½

ㅤ⤀Cos 60⁰ = ½

Therefore,

• Value of Angle x is 60⁰
