Answer 1

Answer:

Y=20° and X=30°

Step-by-step explanation:

Since all the sides given are equal so it's an equilateral triangle

thus all angles are 60° respectively.

hence

3y=60

y= 20°

and 2x=60

x= 30°

Answer 2

Answer:

y=20°, x=30°

Step-by-step explanation:

All the lines of the triangle are equal which means that this an equilateral triangle. Hence, all the angles are also equal.

∴180/3=60°

All angles measure 60°

3y°=60°         2x°=60°

y=60/3           x=60/2

y=20°             x=30°
