Question

if the angels of a triangle are (3x), (2x-7) and (4x-11) then find the value of x​

Answer 1

Supposing angles of triangle as A, B and C respectively.

Summation of angles of triangle is 180°

Putting given angles on A, B and C

Angle A+ Angle B+ Angle C= 180° [Angle addition property]

(3x) + (4x-11) + (2x-7) = 180°

9x - 18 = 180

9x = 198

x = 22

Substitute value of x in all angles, and you can find measure of all angles.
