Question

The third angle of a triangle is the same size as the first. The second angle is 4 times the third. Find the measure of the angles.

Answer 1

Here’s you answer. Hope you will understand by this

Answer 2

Step-by-step explanation:

Third angle = First angle = x

Second angle = 4x

$\implies$ $x+x+4x=180°$ (Angle sum property of triangle)

$\implies$ $6x=180°$

$\implies$ $x=\Large\frac{180}{6}$

$\implies$ $\boxed{ x=30°}$

The angles are 30°,30°, 120°
