Answer:
2 1/2 feet
Step-by-step explanation:
The Pythagorean theorem is not useful in this problem.
__
If you reflect the triangle over the vertical line, you find that line to be the altitude of an equilateral triangle. That is, all of the vertex angles are 60°.
The base of that equilateral triangle is necessarily twice the length of the base of the triangle shown. All sides of the equilateral triangle are the same length, so all are 5 ft. The base of the triangle shown is half that.
The base (short leg) of the triangle shown is 2 1/2 feet.
_____
Since angles are given, this can be solved using trigonometry. The short leg will be (5 ft)·cos(60°) = (5 ft)(0.5) = 2.5 ft. (The cosine of 60° is one of the few exact rational values of trig functions of exact angles measured in degrees.)
Answer:
1/2p+2
Step-by-step explanation:
1/2 distributed to p would be 1/2p. 1/2 distributed to 4 would be the same as 1/2 * 4/1. When you multiply straight across you get 4 in the numerator and 2 in the denominator (4/2). Next you just reduce the fraction, 4 divided by 2 is 2. So, the answer would be 1/2p+2. That answer would go into the 2 empty boxes. Hope thaat helps!!!
Factorize both the numerator and denominator then equate to zero ...you'll get X
The probability of not spinning an even number should be two out of three or 2/3. because there is only 1 even number (2).
