The completed construction of a regular hexagon is shown below. Explain why ACF is a 30º-60º-90º triangle.
LuckyWell [14K]

We know that one regular hexagon is consist of the six equilateral triangles.

One of this is ΔAFM every angle in this triangle worth 60°, according to this

∡AFM=60°.

ΔABC is isosceles triangle with angle ∡ABC=120°, because every interior angle in regular hexagon worth 120°.

Angles ∡BAC=∡BCA=30°. Total sum of angles in one triangle is 180°.

∡ACF≅∡BCA=30° at the end we can conclud that angle ∡FAC=90° WHY?

Good luck!!!

2/3y + v = s solve for y
DanielleElmas [232]

Answer:

y = \frac{3s-3v}{2}

Step-by-step explanation:

Given

\frac{2}{3} y + v = s ( subtract v from both sides )

\frac{2}{3} y = s - v

Multiply through by 3 to clear the fraction

2y = 3s - 3v ( divide both sides by 2 )

y = \frac{3s-3v}{2}
