Question

an exterior angle of a triangle is 105 and its two interior opposite angles are equal find each of these angle.......I'm not getting the sure answer as according to text ans it's 25 1/2​

Answer 1

Step-by-step explanation:

Let two interior opposite angles = x

x + x = 105

2x = 105

x = 105÷2

x = 52.5

This is done by exterior angle property....

You can even verify that of those two angles are 52.5 then the sum of triangle is 180° by Angle sum property...

Doin it for u....

x + 52.5 + 52.5 = 180

x + 105 = 180

x = 180 - 105

× = 75. Then by adding 75,52.5,52.5 we get 180. Pls mark as brainliest if helps.
