Question

2 equal angles of triangle are of measure 70 degrees. Find the measure of 3rd angle.​

Answer 1

Answer:

40

Step-by-step explanation:

70 + 70 =140

180 - 140 = 40

hope it helps ;)

Answer 2

Answer :-

• Third angle = 60⁰

Given :-

• The measures of two angles of a triangular are 50⁰ and 70⁰

To find :-

• Measures of third angle

Solution :-

• Given that, two angles of triangle are 50 and 70

• Let the third angle be x

As we know that:

• sum of all angles of a triangle is 180⁰

Now According to Question:-

• ➝ 50 + 70 + x = 180

• ➝ 120 + x = 180

• ➝ x = 180 - 120

• ➝ x = 60

Hence Third angle is 60⁰

More Explanation :

• sum of all angles of a triangle is 180⁰
• ∠A + ∠B + ∠C
• The three angles in any triangle always make a 180⁰ is iscoscles, right angle , equilateral, scalene triangles.
