Answer:
Step-by-step explanation:
The only way I can solve this is by assuming the letter on the far left is a B. If that is the case, <BAC and <EAC are supplementary.
Ignore the line going from C to D and look at the angle that is left. <EAC is out in the open. What happens is that <EAC and <BAC share the same starting poing which is A.
Each of the angles divide the diameter in two. The construction makes a total angle of 180 degrees which makes them supplementray.
<BAC + <EAC = 180o
<EAC = 31 degrees Given. Substitute that value into the equation above.
<BAC + 31 = 180 Subtract 31 from both sides.
<BAC +31-31 = 180 - 31 Combine
<BAC = 149

Answer:
1/27
Step-by-step explanation:
Okay first, calm down. Math is always hard when your stressed.
First step is to elimate b and write the equation in terms of a. So rearrange a-b=3 to b=a-3. Substitue that into the equation. Now you have :
27^1/3(a-3)
---------------
9^1/2(a)
Now rewrite the equation in terms of 3, you do this by realizing that 9 is simply 3^2 and 27 is simply 3^3. This gives you
3^(a-3)
---------
3^a
Now you use the laws of powers, and you get 3^-3, which is essentially 1/27.

If r= 3 cm, p = 2.4 cm, q = 1.8 cm, and m= 4.35 cm, what is the measure of n?
Answer:
C
Step-by-step explanation:
given the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{LM}{PR}[/tex] = [tex]\frac{LN}{PQ}[/tex] ( substitute values )
[tex]\frac{n}{1.8}[/tex] = [tex]\frac{4.35}{3}[/tex] ( cross- m ultiply )
3n = 7.83 ( divide both sides by 3 )
n = 2.61 cm

three friends Luke nick and serena are kicking a soccer ball to each other on the beach Luke kicks the ball to Serena who kicks the ball to nick, who kicks the ball back to Luke. the friends location on the beach are drawn on a coordinate plane as shown where the x values and y represent distance in feet.
WHAT IS THE APPROXIMATE DISTANCE THE BALL TRAVELS AFTER MAKING A FULL ROTATION AROUND THE TRIANGLE OF FRIENDS?
A. 288 feet
B.57.94 feet
C. 144 feet
D. 67.91 feet
The approximate distance the ball travels after making a full rotation around the triangle of friends is: B. 57. 94 feet.
Total distanceLuke ( 4,10)
Nick (-8, -2)
Serena (4, -14)
Hence:
Distance between two points=√(x2-x1)²+ (y2-y1)²
Distance between Luke and Nick=√ (-8, -4)²+ ( -2-10)²
Distance between Luke and Nick=√288
Distance between Luke and Nick=16.97 feet
Distance between Luke and Serena=10-(-14)
Distance between Luke and Serena=24
Distance between Nick and Serena=√ (-8, -4)²+ ( -2+14)²
Distance between Nick and Serena=√ 288
Distance between Nick and Serena=√16.97 feet
Total distance=16.97 feet+16.97 feet+ 24
Total distance=57.94 feet

If triangle RST and triangle XYZ are similar, which of these equations must be true?
Answer: A
Step-by-step explanation:
If they are similar, that means the proportions for corresponding sides will be the same.
I personally ignore the picture and use the labels of "triangle RST and triangle XYZ" that the problem gives because the XYZ picture is not lined up with the similarity it has with RST.
(A) says that side ST is corresponding with side YZ,
[] Triangle RST and triangle XYZ
-> Correct
(A) also says that side RT is corresponding with size XZ,
[] Triangle RST and triangle XYZ
-> Correct
This means that option A is the correct answer.

a
What is the area of the base of the pyramid?
Answer:
Below in bold.
Step-by-step explanation:
The hexagon is made up of 6 equilateral triangles.
So the Base = 12 cm.
Height a = 12 cos 30 = 10.392 cm
So area of 1 triangle = 1/2 * 12 * 10.392 cm^2
- and total area = 6 * 1/2 * 12 * 10.392
= 36 * 10.392
= 374.11 cm^2 to the nearest hundredth.

Calculate the perimeter of the shape below
Answer: The answer is C ≈ 18.85 meters.
Step-by-step explanation: The formula that you need is...
2 × π (pi or approximately 3.14) × r (which is the radius)
In this case, your radius is 3, so you solve by 2 × π (pi or approximately 3.14) × 3 which equals 18.8495559215 but you round to your nearest hundredth which gets you to have 18.85 meters as your answer! I hope this helps!
radius= 3 m
to find:the perimeter of the circle.
solution:[tex]perimeter = 2\pi \: r[/tex]

Answer:
Step-by-step explanation:
When we add the area of semicircle I and III of same radius, we get a cirlce.
diameter = 48 cm
r = 48/2 = 24 cm
Area of I and III = area of circle
= πr²
= 3.14 * 24 *24
= 1808.6 cm²
Figure II:
length = diameter of the bigger semicircle = 48 cm
width = diameter of the smaller circle = 14 cm
Area of rectangle (figure II) = length *width
= 48 * 14
= 672 cm²
Smaller semicircle A & B
diameter = 14 cm
r = 14/2 = 7 cm
Area of Semicircle A & B = Area of a circle
[tex]\sf = \dfrac{22}{7}*7*7\\\\ = 22*7\\\\= 154 \ cm^{2}[/tex]
Area of shaded region = area of rectangle II + area of figure I & III - area of A &B
= 672 + 1808.6 - 154
= 2326.6cm²
