Question

The measure of two angles of triangle are 60° and54°. Find the measure of the third angle.

Answer 1

Answer:

we know that triangle make angle of 180degree

60+54+c=180

114+c=180

c=180-114

c=66degree

Answer 2

Answer:

solution:

measure of one angle =60°

measure of another angle=54°

measure of 3 angles=180°(angle sum property of a triangle)

measure of third angle=180°-(60°+54°)

180°-114°=66° (ans)
