The sum of all the angles in a triangle is 180 degrees. The triangle in the picture is also an equilateral triangle because of the markings on it (the three arches and ticks show that the sides with the markings are congruent.)

So since an equilateral triangle has 3 angles and the angles are congruent, we can divide 180 by 3 to find out how many degrees each angle is; 60 degrees.

Since all angles are equal, angle A = angle B = angle C = 60 degrees.

In the figure below,S is between Q and T and R is the midpoint of QS. If RS=4 And RT= 12 find QT

Oxana [17]

Qt = 16.

Because since rs Is equal to qr since r is the midpoint of qs. So qr is 8 and because s is the midpoint of the whole line. I multiply it by 2. Giving me 16 for the whole line

Star Wars land encompasses an area of 14.0 acres. [1.00 acre = 4046.86m2]. If Star Wars land were made into a circle, what would

Free_Kalibri [48]

Answer:

<h3>The answer is 134.29 m</h3>

Step-by-step explanation:

First of all we need to convert 14.0 acres to m²

1.00 acre = 4046.86 m²

14.0 acres = 14 × 4046.86 = 56656.04 m²

Area of a circle = πr²

where

r is the radius

To find the radius substitute the value for the area into the above formula and solve for the radius

That's

$56656.04 = \pi {r}^{2}$

Divide both sides by π

We have

${r}^{2} = \frac{56656.04}{\pi}$

Find the square root of both sides

$r = \sqrt{ \frac{56656.04}{\pi} }$

r = 134.29139

r = 134.29 m to 2 decimal places
