It's either 0.354249 or 5.645751 I hope this helped. (Btw both are correct I just simplified them from 3+<span>√7 and </span>3−<span>√<span>7)</span></span>
They use place value to determine which 7 is 7,000 or 70.
Answer:
5040
Step-by-step explanation:
There are 7 options for the 1st song, 6 options for the 2nd song, 5 options for the 3rd song, 4 options for the 4th song, 3 options for the 5th song, 2 options for the 6th song, and 1 option for the 7th song. We get:
(<em>Note: when you have a number n, where it is multiplied by every number until one (ex. 7. 7*6*5*4*3*2*1), then the number in the result is n! (n factorial). So we get that 7*6*5*4*3*2*1 is 7! is 7 factorial. So 5040 is 7! </em>)
Answer:
Side A = 14; Side B = 24.25; Side C = 28 |
Angle A = 60 degrees; Angle B = 30 degrees; Angle C = 90 degrees
Step-by-step explanation:
Okay, I find this question a bit weird because you already have two sides
So, I'm going to assume:
Side A = 14
Side B = 24.25
<h3>Finding side C</h3>
Using Pythagoras theorem
c = 28 units (28.00111605)
<h3>Finding Angles (A,B and C)</h3>
In the diagram, we can see there is a right angle triangle, and a little square
Therefore, we can say that Angle C is 90 degrees
Finding Angle A/B:
There are so many ways to find it, I'll just use this though
<h3>Method: Using SOHCAHTOA to find B, then finding A</h3>
Using SOHCAHTOA
I'll be using the sine rule to find Angle B
Angle B = 30 degrees
The interior angles in a triangle add up to 180 degrees
Angle A = 180 - (90 + 30)
Angle A = 60 degrees
Verify:
60 + 30 + 90 = 180
