Question

If two angles of triangle are 43 and 61 respectively. Find the third angle​

Answer 1

Answer:

76 DEGREES

Step - by - Step Explanation:

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

Here, we know the values of two angles = 43 degrees and 61 degrees.

Let the unknown angle be x. Therefore,

43 + 61 + x = 180 degrees

104 + x = 180 degrees

x = 180 - 104

   = 76 degrees

So, the measure of the third angle of the triangle is 76 degrees.

Answer 2

Answer:

S76 DEGREES

Step - by - Step Explanation:

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

Here, we know the values of two angles = 43 degrees and 61 degrees.

Let the unknown angle be x. Therefore,

43 + 61 + x = 180 degrees

104 + x = 180 degrees

x = 180 - 104

  = 76 degrees

So, the measure of the third angle of the triangle is 76 degreestep-by-step explanation:
