If you separate the triangles, you'll notice that both are literally the same triangle because all angles are the same.

Answer:

Since the triangle is an isosceles triangle we know the long two sides are equal to each other. This means if we cut the triangle in exactly half, the two right triangles will be congruent to each other. This works since the triangle is an isosceles triangle.

how would the fraction 5÷1-√(3 be rewritten if it's denominator is rationalized using difference of squares

Lunna [17]

What you would do is use the 'difference of two squares' principle to identify the binomial (two-term) expression that will multiply by (1 - √3) to give only a number as a rational number cannot be a surd.
However, you cannot simply multiply just the denominator as this would alter the value of the expression so what you have to do is multiply the expression by the fraction that is: 'found binomial expression' / 'found binomial expression', which is simply equivalent to 1 and so the value of the original expression will not be changed.
So, how do you find the 'binomial term':
All you have to do is invert the sign, so the binomial term will be:
(1 + √3)

So you now just multiply the original expression by (1 + √3)/ (1 + √3) and simplify of course.

A square has an area of 49 sq in. How do you find the perimeter?

lutik1710 [3]

Answer:

The perimeter is 28 in.

Step-by-step explanation:

We know that the area is 49 square inches and that the area of a square equals length times width. Also, all sides of a square are equal. 7 times 7 equals 49, so the length and width are both 7 inches. The perimeter is equal to all the sides added together. There are four sides in a square, and we know that each side is 7 inches. Therefore, we can add 7+7+7+7 (or multiply 7 times 4) to get the square’s perimeter: 28 inches.

ANSWER ASAP The questions on a multiple-choice test each have 5 answer choices.

Len [333]

Answer:

F, spinning a spinner with five equal sections

Step-by-step explanation:

The probability of something is (the ways to acheive the wanted outcome / all possible situations)

For example, the probability of getting heads on a coin flip is (1 possible way to get heads / 2 possible outcomes) = 1/2, or 50/50

Now, onto the problem.

There is only one way to get the answer right, and 5 possible situations. So, the probability of getting the question right would be 1/5.

F) Spinning a spinner with five parts means that you have: 1 way to get the right section, and 5 possible outcomes. So, the probability of getting the right section would be 1/5. So, this answer is correct.

G) Flipping a coin five times: Each time, you have a 1/2 chance of the coin landing on the desired side. So, this would not be an accurate comparison.

H) Spinning a spinner with four equal sections: There is one way to land on the desired section, and 4 possible outcomes. So, the probability of this simulation is 1/4, so this answer is incorrect.

I) Rolling a number cube labeled one through six times: Each time, there is one way to land on the number you want, while there are six possible outcomes. So, the probability of getting your desired number is 1/6, which is incorrect.

I hope this helps! Feel free to ask any questions!
