Answer:

(a) = 60

(b) = 70

Step-by-step explanation:

(a) Sum of all the angles of a triangle is 180

This is an equilateral Triangle

which means all the sides are equal since all the sides are equal that means all the angles are equal

x + x + x = 180 \\ 3x = 180 \\ x =  \frac{180}{3}  \\ x = 60

(b) this is an isosceles triangle with two equal sides that means the two opposite angles are equal

40 + x + x = 180 \\ 40 + 2x = 180 \\ 2x = 180 - 40 \\ 2x = 140 \\ x = 70
