Question

One angle of a triangle is 2 more than thrice the other angle. If the third angle is 38", find the angles of the triangle​

Answer 1

Step-by-step explanation:

one angle = 3x+2

second angle = X

third angle = 38

( sum of angles of triangles is 180°)

3x+2+X+38 = 180°

= 4x+ 40 = 180°

= 4x= 180° - 40

= 4x= 140

= X = 140/4

therefore , X= 35

second angle is 35°

first angle is 3(35+2)

= 107

hence, first angle is 107

third angle is 38

proof : 35+107+38

= 180°
