Question

What is the value of third angle if the two angles of a triangle are 43° and 67°?​

Answer 1

Answer:

70

Step-by-step explanation:

sum of angles of triangle=180

180-(43+67) =70

Answer 2

The value of 2 angles of a triangle is given to be 43° and 67°

We have to find the third angle

Let us assume the third angle to be x

So, we know that the sum of angles in a triangle is 180°

x + 43 + 67 = 180

      x + 110 = 180

              x = 180 - 110

              x = 70

Hence, the third angle of the triangle will be 70°
