Question

The two angles of a triangle are 60⁰ and 70⁰, what is the third angle ?​

Answer 1

Given:

• The two angles of traingle are 60° and 70°

To Find:

• Third angle

Solution:

• Let the third angle be x°

We know that sum of all angles of triangle is 180°

60° + 70° + x = 180°

• (Using angle sum property)

➠ 130° + x = 180°

➠ x = 180 - 130

➠ x = 50°

Hence, Third angle of traingle is 50°

Answer 2

Answer:

50°

Step-by-step explanation:

Sum of all angles in a triangle is 180°.So as given in the question the two angles are 60°and 70°.

Let the third angle be x

60°+70°+x=180°

130°+x=180°

x=180°-130°

x=50°

So the third angle will be 50°
