Question

re the following questions:
If two angles of a triangle are 30 and 80. then find the third angle.
​

Answer 1

Answer:

Step-by-step explanation:

let the third angle be x.

80+30+x=180 degrees.

Because we know that sum of all angles in a triangle is 180

=>110+x=180

=>x=180-110.

=>x=70 degrees.
