<span>Rational
expressions are defined as the quotients of two integers in which the
denominator does not equal to zero. Thus, the numerator and denominator would
be polynomials, which is a form of a system analogous to the integers under the
operation of addition, subtraction and multiplications. Therefore, the key
numbers of rational expressions are its variables in the numerator and/ or
denominator.</span>
Answer:
22.5°
Step-by-step explanation:
The triangle is an equal 1/8 slice of the octagon. If another triangle were placed right next to it, it would have the same angle. so to find out the angle, we just have to divide it by 2.
45 ÷ 2 = 22.5
The length of the ladder is 13 because: using the pythagorean theorem
a² + b² = c²
5² + 12² = c²
25+144 = 169
169 = c²
Then figure the square root of 169.
13 x 13 = 169
Hope this helps :)
Answer:
c is the answer. (Assuming that's a positive 5)
Step-by-step explanation:
You would use the slope formula: (y1 - y2)/(x1-x2).
Plugging in gives
(3--2)/(2-1)
(3+2)/(2-1)
which simplifies to:
5/1
= 5
Hope this helps!
