sin a = 172/N
N is ≈ 174.951
so
sin a ≈ 172/174.951 ≈ 0.983
Is that not the right answer?
Multiplication comes before addition, therefore:
5 + 2*10
= 5 + 20
= 25
sin A = a/c
cos A = b/c
tan A = a/b
similarly:
sin B = b/c
cos B = a/c
tan B = b/a
You can remember this with " SOH CAH TOA. "
Sine of an angle = length of leg Opposite that angle divided by the length of the Hypotenuse
Sin = Opposite / Hypotenuse
Cosine of an angle = length of leg Adjacent that angle divided by the length of the Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent of an angle = length of led Opposite that angle / length of leg Adjacent that angle
Tangent = Opposite / Adjacent
Remember this only works on right triangles! And the "adjacent" leg cannot be the hypotenuse.

1% of 16,000,000,000,000 = (0.01)(16,000,000,000,000) = 160,000,000,000
160,000,000,000 = how much you pay per year
160,000,000,000/365 ≈ 438,356,164
438,356,164 ≈ how much you pay per day
Write it in fraction form and then reduce it if necessary.
For example, 0.8 is eight tenths. 8/10 = 4/5
and
0.346 is three hundred forty-six thousandths. 346/1000 = 173/500
Just like that :)
Press the "2nd" key in the top left.
Alternatively, if you're on a computer you can press and hold "shift" or press and hold the key that you want to get the inverse of.
Nice!! Here's 5 more points x)
Look at the fraction: 1/8. 1 is less than half of 8, so 1/8 is less than half of 1. If you have 1/8th of a cookie, you have less than half of one cookie. So 5 and 1/8 rounds down to just 5.
If the numerator is less than half the denominator, just drop the fraction. If the numerator is greater than or equal to the denominator, round up by adding one to the whole number.
For example: 7 and 9/10 rounds up to 8 because 9 is bigger than 5. 9/10ths of a cookie is almost a whole cookie. If you have a cookie and break it into ten pieces, nine of them is almost all of it. So 7 and 9/10ths cookies is almost 8 cookies.
Hope this made sense :)
Brad bought a computer for $453 and a printer for $96. So Brad spent a total of $453 + $96 = $549.
Maria bought a television for $399 and a DVD player for $148. So Maria spent a total of $399 + $148 = $547.
Brad spent $549. Maria spent $547.
Which is greater, $549 or $547 ?
