Question

In a triangle one of the exterior angle is 105°. one of the interior opposite angle is 75°. find the measure of all the angles of the triangle.

with solutions ​

Answer 1

Answer:

Okay dear it's easy..........

Step-by-step explanation:

exterior angle = sum of two opposite interior angles

105° = 75° + sum of opposite interior angle

sum of opposite interior angle = 105° – 75°

= 30 °

sum of all angles of triangle = 180 °

so,

x + 75°+30° = 180°

x = 180° – 105

x = 75°

so, all the angles are.

75°, 75°, 30°
