Question

08. a) /f all the three angles of a triangle are equal to one another. Then find the measure of each angleb) Two angles of a triangle are of measure 60' and 75º. Find the measure of the third angle​

Answer 1

Step-by-step explanation:

a) given: all the three angles are equal

to find: measure of each angles

solution: let all the three angles be x

x+x+x = 180° ( angle sum property of triangle)

3x= 180°

x= 180°/3

x= 60°

all the angles of the triangle are of 60°

b) given: Two angles of a triangle are of measure

60' and 75º

to find: measure of 3rd angle

solution : let the third angle be x

60° +75°+x= 180° (angle sum property of triangle)

135°+x= 180°

x= 180°-135°

x= 45°

third angle is of 45°
