Umm..... according to what I know <span> </span><span>The ratio of the sides of a 30°-60°-90° triangle are:
short leg : long leg : hypotenuse
1 : √3 : 2
</span><span> if the short leg is 7, the long leg is √3 times that:
Answer:
7√3 ≈ 12.12 inches </span>
The answer would be D.
you would start by choosing one of the variables to eliminate, i chose to eliminate X first. in order to eliminate X, i had to multiply the second equation by -2. X then cancelled out, and i solved for the Y the same way you would a 1 step equation. Y=-4
I then took the first original equations, plugged Y in, and solved for X. X=3.
Hope this helps!
Ok!
1st box : 6 and 3/8
2nd box : x
3rd box : 8
A rectangle is a four sided figure with four right angles but it does not have congruent sides because two of its sides are longer than the other two.
30-10=20
20-10=10
or
10+20=30
