Question

two angles of a triangle are equal to the third angle measures 70° find the measure of each of the unknown angles which of the

Answer 1

Two angles of a triangle are equal, let x°+x°

Third angle is 70° [Given]

Now, find unknown angles-

solve- x°+x°+70°=180°

        =2x°+70=180

        =2x°=180-70

        =2x°=110

        =x°=110/2

        ∴=x=55° ans.
