Question

23) Triangle ABC is a right angled triangle at B. ∠A = 2x and ∠C = x. Find the
value of x and also the measure of all the angles of thetriangle.

Answer 1

Answer: x = 30⁰ . A = 60⁰ C = 30⁰

Step-by-step explanation:

Here,

A = 2x

C = x

B = 90⁰( Since ABC is a right angled at B )

Now ,

A+B+C = 180⁰(Angle sum property)

=>2x + 90⁰+ x= 180⁰

=> 3x = 90⁰

=> x = 30⁰

Therefore ,

A = 2*30⁰= 60⁰

C = 30⁰
