Answer 2

1st triangle :

Angle sum property ( Sum of all angles in a triangle = 180°)

Angles in the 1st triangle = 3x, 2x and x

So,

$x + 2x + 3x = 180 \\ 5x = 180 \\ x = \frac{180}{5} \\ x = 36$

So, x = 36 °

2nd triangle :

Angle sum property

Angles in the triangle :

a - x°

b - 50°

c - also 50° ( because, side b and side c are equal)

So,

$x + 50 + 50 = 180 \\ x + 100 = 180 \\ x = 180 - 100 \\ x = 80$

Therefore, the value of x = 80°
