Question

1) The measure of angles of a triangle are 2x⁰+(x+45⁰)+(x-20⁰),find the measure of each angle​

Answer 1

Answer:

77.5 , 83.75 ,18.75

Step-by-step explanation:

sum of angles in the triangle = 180°

2x °+ (x+ 45)°+ (x-20)°= 180°

4x + 25° = 180°

4 x = 180°- 25°

4x = 155°

x= 155°/4

x =38. 75°

angles= 2x ° , (x+ 45)° ,(x -20)°

= 2× 38.75 °, 38.75° + 45° ,38.75° - 20°

= 77.5° , 83.75° , 18.75°
