Question

10. If two angles of a triangle are


62

and


38

, then the third angle of triangle is____.​

Answer 1

Answer:

let the 3 rd angle =x

we know 62+38+x=180

100+x=180

send 100 to the side of 180

x=180-100

therefore X=3rd angle =80

Answer 2

Answer:

Step-by-step explanation:

the sum of all the angles of a triangle is 180

so,let the unknown angle be x

62+x+38=180

x+100=180

x=80
