Question

Two angles of a traingle are of measure 60 and 75 find the measure of third angle

Answer 1

Answer:

45

Step-by-step explanation:

60+75+x=180

135+x=180

x=180-135=45

Answer 2

Answer:

Let the third angle be x°

According to the question,

60° + 75° + x 180° (Angle sum property)

135° + x = 180°

x = 180° - 135°

x = 45°

∴ The measure of the third angle is 45°
