Question

PLEASE HELP!
Finding x and y based on the triangle, please show work.
(Geometry)

Answer 1

Above triangle is an equilateral triangle.

• All the sides and anglesof thia triangle are equal.
• This is all given by the dashes on the sides of the triangles.

This means that

`y + 3 = 2y - 5`

Lets us solve for y.

`y - 2y = - 5 - 3 \\ - y = - 8 \\ ( - y)/( - 1) = ( - 8)/( - 1) \\ y = 8`

All three angles are equal in an equilateral triangle.

this means that if given that one angle is 10x° then all the other 2 angles are equal to 10x°

`10x + 10 x+ 10x = 180 \\`

Sum of all interior angles of a triangle is 180°

Let us solve for x

`30x = 180 \\ (30x)/(30) = (180)/(30) \\ x = 6`

x=6°
