Number 1 and 2 with full process plzzzzzz

Answer 1

Answer:

1.a)The other two angles of a right-angled isosceles triangle will be equal to each other, since angles opposite to equal sides are equal.

 b)Yes, u can. For example, 100°+40°+40°= 180°.Therefore the sides opposite to 40° are equal.

2.a)One of the angles= 110°

     Other two angles= x and x (isosceles)

     => x+x+110= 180

     =>2x=70=>x=35°

     => ∴ each of its base angles must be 35°

   b) Each exterior angle of an equilateral triangle= 180 - 60( measure of                         each exterior angle is 60°)

   =>180 - 60 = 120°
