Question

An exterior angle of a triangle is 105 degrees and its interior opposite angles are equal find the equal angles.​

Answer 1

Answer:

52.5 deg

Step-by-step explanation:

the sum of two interior angles is equal to the opposite exterior angle.

here the interior angles are equal.

Therefore their sum = 2*x where x is the interior angle

2*x = 105 deg

x = 105/2 deg

x = 52.5 deg

Answer 2

Step-by-step explanation:

180-105=interior angle ( linear pair)

75

int. opp. angles are equal

= 2x + 75 =180

equal angles = 52.5
