Question

Two angles of a triangle are of measures 119 degree and 40 degree . Find the measures of the third angle

Answer 1

Answer:

the third angle is 21

Step-by-step explanation:

119+40+third angle=180..........(the sum of measure of all angles of a triangle is always 180°.)

159+third angle=180

third angle=180-159

third angle=21

Answer 2

Answer :

Third angle = 21°

Step-by-Step Explanation :

→ Angle sum of a triangle is 180°

Two of the angles are 119° and 40°

Let, the third angle be x°

So, we got an equation to compute, i.e -

x° + 119° + 40° = 180°

x + 159 = 180

x = 180-159

x = 21°

∴ the third angle is 21°
