Question

two angles of a triangle are of measure 60 degree and 45 degree, find the measure of the third angle ​

Answer 1

Let the required angle be x

according to Angle Sum Property

45 + 60 + x = 180

x = 180 - 105

x = 75 degrees .

Answer 2

Answer:

75°

Step-by-step explanation:

sum of all angles of a triangle is 180°

so,45°+60°+x=180°

x=180°-105°

=75°
