Question

determine the value of each of the following triangles. figure 10.explain​

Answer 1

Answer:

x=12, angles of triangle= 24,36,120

Step-by-step explanation:

5x=2x+36     [Exterior angle property of triangle]

=>3x=36

=>x=36/3=12

5x+3rd angle=180    [Straigtht line]

5*12+3rd angle=180

60+3rd angle=180

3rd angle=180-60=120

2nd angle= 2x=2*12=24
