Answer:

FALSE

Step-by-step explanation:

The answer is false because the length between DC is 6 and the length between EB is 8. If the lines were parallel, both lines would have the same length.

Can you find both the value of x and y? It is a 30-60-90 triangle
Juli2301 [7.4K]

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!

Alina has 15x + 12 yards of ribbon. She uses 6x - 3 yards for a project. How many yards does she have left?
Andrews [41]

Answer:

-1.66666666667 yards

Step-by-step explanation:

15x+12=6x-3

subtract 6x on both sides

9x+12=-3

subtract 12 on both sides

9x=-15

x=-1.6666666666667

Please help I’m lost it has to be 3 or 2 or more answers by the way and I will except answers from Expert, Ace, or Genius or any
deff fn [24]
The correct answer is only A, because you need the tenths place to be greater than the number on the left, and not just the hundredths place.

P.S. Even though I'm a beginner, I took Multi-Variable calculus in 12th grade.
P.P.S. STOP PUTTING ON RANDOM ANSWERS ON QUESTIONS JUST SO YOU CAN GET THE POINTS!!!!!!
