Question

In triangle ABC, ∠A:∠B: ∠C = 1:2:3 then find the A​

Answer 1

Answer:

let us consider ∠A as x , ∠b as 2x and ∠C an 3x

∠a+∠b+∠c=180°(sum of the measure of triangle is 180°)

x+2x+3×=180°

6x=180

x=180/6

x=30

∠A=30

∠B= 2x= 2×30 =60

∠C= 3x=3×30=90

make sure u add therefore sign✌️

Answer 2

Answer:

30 degree

Step-by-step explanation:

Let angel A, B, and C be x, 2x and 3x respectively

we know that the sum of all angles of a triangle is 180 degree

then,

A+B+C=180

=> x+2x+3x = 180

=> 6x =180

=> x = 30
