Question

please tell me the answer because it is urgent please ​

Answer 1

As we know that sum of angles of a triangle is 180° (as per angle sum property)

so,

(2x+15)° +( x+10)°+ (3x +5)°=180°

(6x +30)°=180°

6x =180-30°

6x=150°

x=150/6

x=25°

so (2x+15)°= (2X 25+15)°=75°

(x+10°) =25+10° =35°

(3x+5)°= (3X25+5)° = 75+5°= 80 °

hope it will help you...
