Question

5. One of the angles of a triangle is 110° and the other two angles are equal. What is the
is equal to the sum of other two, show that the triangle is a right​

Answer 1

solution:

we know that;

sum of all three angles in a triangle is equal to 180°.

here,

let equal angles are = x

Now,

sum of angles = 180°

=> x + x + 110° = 180° =

=> 2x = 180° - 110° = 70°

=> angle x = 35°

hence

Angles of triangle are :

35°, 35° and 110° Answer
