Question

two angles of a triangle are 30 degree and 80 degree. find the third angle

Answer 1

Heya here's ur answer
We know that all the angles of a triangle equal to 180°

so 30°+80°+3rd angle=180°
now,
let the third angle be x
so 30°+80°+x=180°
so x=180-110
so x=70°
hope it helps you dear

Answer 2

Hey bro here is your answer...
Using the angle sum property of triangle ...
It states that the sum of all angle of a triangle is 180 degree
ATGQ
30+80+x=180
110+x = 180
x= 180-110
=70 degree
So, the third angle of triangle is 70 degree
