Question

pls answer this one​

Answer 1

Step-by-step explanation:

Let the angles be 1x ,2x,1x

x+ 2x + x= 180° ( Angle sum property of triangle)

4x= 180°

x= 180/4

x= 45°

=) x= 45°

2x= 2 × 45= 90°

x= 45°

hope it helps

Answer:

let the sides be x

angle 1 :x

angle 2 : 2x

angle 3 : x

x+2x+x : 180°

4x : 180°

x : 45°

angle 1 : 45°

angle 2 : 90 °

angle 3 : 45 °
