Answer 2

Step-by-step explanation:

EXTERIOR ANGLE OF THE TRIANGLE= 105 DEGREES

AND BOTH the Interior angles are equal..

let both the equal angles be x degree each

then ,

=> 105° = x°+x°   ∵(exterior angle of a triangle is equal to the sum of interior opposite angles..)

∴ 105° = 2x°

105/2 = x°

therefore,

x° = 52.5°
