Question

the angle of triangle are (x-40 ), (x-20) and (1/2x-10) find all angle of triangle
​

Answer 1

Step-by-step explanation:

ans is 40 hope it help youuuu

Answer 2

Answer:

x-40+x-20+1/2x-10=180°

x+x+.5x-40-20-10=180°

2.5x-70°=180°

2.5x=250

x=100

so,

1st angle x- 40

100 - 40 = 60°

2nd angle x- 20

100 - 20 = 80°

3rd angle .5x - 10

50 - 10 = 40°

so all the 3 angles of the triangle are 60° 80° and 40°
