Answer:

the sum of all the angles of a triangle is 180°

so, let the measure of the third angle be x°

according to the question-

30° an 70° are the other two angles of the triangle

so,

30°+70°+x°=180°

100+x°=180°

x=180-100

x=80°

Step-by-step explanation:

therefore the third angle of the triangle=x°=80°

given:- here in this question, two angles of triangle is given and we have to find the value of the third angle.

⇒ 1st angles=30° , 2nd angle= 70° .

TO FIND:- we have to find the third angle, as we are given with two angles, and value of 3rd angle=?.

SOLUTION:-

"We know that the sum of all the angles of a triangle is 180°."

 Let the third angle of the triangle be x° then,

 ∴30°+70°+x°=180°

⇒100+x°=180°

⇒x=180-100

⇒x=80°.

HENCE, the value of 3RD ANGLE=x=80°

Therefore, third angle= 80°
