Answer:
The diagrams below explain the process with angles.
Step-by-step explanation:
In figure 1, a rectangle is drawn in the circle.
Since the acute angle being drawn by the hypotenuse is 40 degree in figure 2, thus we can say the other angle will be 50 degrees.
In figure 3, the rectangle is cut across its diagonal to form a kite shaped entity within the circle.
Now we know that m∠BDE = 40° = m∠ADB.
Also, m∠A = m∠E = 90°
Thus, m∠EBD = m∠ABD = 50° ⇒ m∠B = 100°
Also, m∠ADE = 80° ANSWER
Let's imagine that we have in the deck 52 cards. So what we need to do is to make a kind of "progression".So let me explain this by doing the procedure. we can use is like this:
4/52 * 3/51 * 2/50 * 1/49 =
<span>24 / 6497400 = </span>
<span>1 / 270725 </span>
<span>3.694e-6</span>
Answer:
(3,1) is the answer your looking for.
Step-by-step explanation:
Answer:
6 runners
Step-by-step explanation:
Each runner ran 7.5 km. If there were n runners, then (7.5 km)n = 45 km.
Solve this for n by dividing 7.5 km into 45 km:
n = 6
There were 6 runners.
The first step would be :
E) 3x + (2x + 4) = -7
