Question

The angles of a triangle are in the ratio 4: 3: 2. Then the measure of the largest angle is ________.​

Answer 1

Answer:

let angles be= 4x, 3x and 2x

4x+3x+2x= 180 degree (angle sum property of triangle which states sum of all the angles of a triangle is 180 degree)

9x= 180 degree

x= 180/9

x= 20 degree

first angle= 4*20= 80 degree

second angle= 3*20= 60 degree

third angle= 2*20= 40 degree

measure of largest angle is 80 degree
