5 out of 6 is the chances NOT to roll a 5.
Approximately 83.33% of a chance to NOT roll a 5.
Answer:
171 degrees
Step-by-step explanation:
If angle POS is 39 degrees, then the measure of arc PS is 39 degrees
You can apply this to arc SQ and QR
So:
39+90+42= measure of arc RPQ
171 degrees= measure of arc RPQ
Answer:
A. 3/10
Step-by-step explanation:
So the ratio is saying 2 units to 3 units. What represents 1 unit when 1/5 is two units? We cut it in half which is 1/10.
Now we have 1 unit so we can easily find three by multiplying by three, or even just adding three together. So that's 3/10.
let me knowif you don't quite get it.
I) 156 degrees
The exterior angle is 180-156
=24
The number of sides=
The number of sides= 15 sides
ii) 162 degrees
The exterior angle= 180-162
=18
The number of sides=
= 20 sides

Answer: cos(76)</h3>
=========================================================
Explanation:
The original expression is of the pattern cos cos + sin sin. This pattern matches the second identity in the hint. Specifically, we'll say the following:
cos(A - B) = cos(A)cos(B) + sin(A)sin(B)
cos(A)cos(B) + sin(A)sin(B) = cos(A - B)
cos(94)cos(18) + sin(94)sin(18) = cos(94 - 18)
cos(94)cos(18) + sin(94)sin(18) = cos(76)
----------
We can verify this by use of a calculator. Make sure your calculator is in degree mode.
- cos(94)cos(18) + sin(94)sin(18) = 0.24192
- cos(76) = 0.24192
Both expressions give the same decimal approximation, so this helps confirm the two expressions are equal. You could also use the idea that if x = y, then x-y = 0. Through this method, you'll subtract the left and right hand sides and you should get (very close to) zero.
