Question

If the measures of two angles of a triangle are 52° and 78°, find the measure of the third angle.
​

Answer 1

Answer:

50

Step-by-step explanation:

Let the angle be x

52+78+x=180

130+x=180

x=180-130

x=50

Answer 2

Answer:

• Third angle of triangle is 50°.

Step-by-step explanation:

Given:-

• Measure of two angles = 52° & 78°

To Find:-

• Measure of third angle

Solution:-

Let the third angle be x.

As we know that sum of all angles in triangle is 180°

we have to calculate the third angle of the triangle . Substitute the value we get

→ 52° + 78° + x = 180°

→ 130° + x = 180°

→ x = 180°-130°

→ x = 50°

• Hence, the third angle of the triangle is 50°
