There's a very simple rule for geometries like this. The measure of the arc is double the measure of the angle. It helps to remember this.

Your angle is 65°.
The measure of the arc is 2×65° = 130°.

You need to use the central angle.
If you know the radius or how CD works (does it go through the center), then  the answer will be less vague. The central angle = 2 * 65 = 130
the length of BC is 

130/360 * 2*pi*r
13/18 * pi r is the general answer.

Type the expression that results from the following series of steps:
kvv77 [185]

Answer:

\frac{x - 3}{6}

Step-by-step explanation:

First, subtract 3 from x

This will get you the expression x - 3

Now, divide this by 6.

This will get you the expression \frac{x - 3}{6}

So, the final expression from the steps is \frac{x - 3}{6}

aev [14]
The base is 44 cut that in half to get the radius, R=22 height=6 
fill in v=1/3 x 3.14 x r^2 x H
v = 1/3 x 3.14 x 22^2 x 6
22 x 22= 484
484 x 6 = 2904
2904 x 3.14= 9118.56
9118.56 x 1/3 = 9118.56/1 divided by 2735568/3 = 300

Given: m angle P equals open parentheses 5 x minus 27 close parentheses degree, m angle Q equals open parentheses 4 x minus 7 cl
max2010maxim [7]

Answer: Side QR

Step-by-step explanation: The sum of a triangle internal angles is 180°. So to determine the angles, we calculate x:

5x - 27  +4x - 7 + 3x + 10 = 180

12x = 204

x = 17

With x, solve for the angles:

m∠P = 5(17) - 27 = 58

m∠Q = 4(17) - 7 = 61

m∠R = 3(17) + 10 = 61

The relationship between angles and sides in any triangle:

  • the largest angle is opposite the largest side;
  • the middle angle is opposite to the middle-sized side;
  • the shortest angle and side are opposite to each other;

So, the shortest side of PQR is the side opposite to the shortest angle.

The shortest angle is m∠P = 58°. Therefore, the shortest side is QR
