Question

how do i solve this ?please explain how to solve.​

Answer 1

Answer:

since all sides are equal

so all angles are also equal ( equilateral ∆ )

and each angle is 60°( property of equilateral ∆)

=} 2x = 60°

=} x = 60°÷2

=} x = 30°

__________________

=} 3y = 60°

=} y = 60÷3

=} y = 20°

hope it will help u lot

Answer 2

Answer:

all sides of this triangle is equal. This means this is an equilateral triangle.

We know that all angles of equilateral triangle are equal (each measures 60⁰).

so, 3y⁰= 60⁰

y⁰= 60⁰/3

y⁰ = 20⁰

and,

2x⁰ = 60⁰

x⁰ = 60⁰/2

x⁰ = 30⁰

Hence, y⁰ = 20⁰

x⁰ = 30⁰

verification

3y⁰=3×20⁰= 60⁰

2x⁰=2× 30⁰= 60⁰
