A triangle has two sides measuring 16 and 21. The included angle is 116°. What is the length of the side opposite the 116° angle
Crank

Answer:

Length of the side opposite to angle 116^{\circ} is 31.49

Step-by-step explanation:

Included angle can be defined as the angle in between two sides of the triangle.

So angle 116^{\circ} is in between sides 16 and 21.

Refer to the attachment for triangle diagram.

To find the length of opposite side, use cosine rule as follows

a^{2}=b^{2}+c^{2}-2\:b\:c\cos\left(A\right)

From the diagram, b = 21,c = 16,\angle A=116^{\circ}

Substituting the values in the formula,

a^{2}=\left(21\right)^{2}+\left(16\right)^{2}-2\left(21\right)\left(16\right)\cos\left(116\right)

Simplifying,

a^{2}=441+256-225792\left(-0.44\right)

a^{2}=991.59

Taking square root on both sides,

\sqrt{a^{2}}=\sqrt{991.59}

a=31.49

Therefore length of third side is 31.49

Select the correct answer from each drop-down menu. Rafael wants to construct a square inscribed in a circle. He divides the cir
Soloha48 [4]

The circle's square is an inscribed square.

  1. Rafael made his first error in (B) Dividing the circle in six parts.
  2. The square can be constructed by first (c) Drawing a diameter
<h3>How to spot Rafael's mistake?</h3>

CIRCLE: A circle is the collection of all points on a plane that are at a specified distance from another point (the radius) (the centre). A radius is any distance separating a point on a circle from its center. Any two radii are equal in length under the concept of a circle.

SQUARE: In geometry, a square is a flat shape having four equal sides & four right angles (90°). A square is an unique sort of parallelogram as well as an equilateral rectangle.

Estimation for the error;

The diameter of a circle must be drawn first when drawing the square inside of a circle, following the circle itself.

This indicates that Rafael made two mistakes: first, he divided the circle into six halves, forgetting that a square is produced by first sketching a diameter.
