D) 34/5 because 6(5) = 30 30+4=34 , so its 34/5
Answer:
x = 8*root3
y = 16
Step-by-step explanation:
You can use tangent and cosine of 60° to find x and y, BUT THERE'S A SHORTCUT. You pointed out that its a 30°-60°-90° triangle. That is a special right triangle. Here's the shortcut:
the longest side (hypotenuse) is double the shortest side. We have an 8 on the shortest side, so the hypotenuse (longest side) is 16. This ALWAYS works for 30°-60°-90° triangles!
Another shortcut:
The longer leg is the shorter leg × root3.
This ALWAYS works on 30°-60°-90° triangles.
So on your triangle, the short side is 8, that means the longer leg is 8×root3.
ta-daaaa!
Answer:rational
Step-by-step explanation:
2) 
is a rhombus (a parallelogram with perpendicular diagonals is a rhombus)
3) 
bisects 
(diagonals of a rhombus bisect the angles from which they are drawn)
Darn it i was looking for the same thing
