Answer» First take an angle to be x and it is giving energy that it is equal to its other two angle take them to be y and z by using angle sum property of triangle. x +y+z=180 x+x=180 (y+z=x)2x=180x=180/2x=90hence proved X = 90May this help you let a be 90degreethen a+b+c=180 asPthen A+b+c=180b+c=90 |
