Answer:
11/-30 Hope this helped :)
Step-by-step explanation:
15x + 4 = -1 1/2
15x = -5 1/2
x = 11/-2*1/15
x = - 11/-30
The length of the third side is 3.6 units
Let the sides of the triangle be;
x, y and z
So, we have:
x = 3
y = 4
<Z = 60
The length of the third side is then calculated using the following law of cosine
z^2 = x^2 + y^2 - 2xy cos(Z)
So, we have:
z^2 = 3^2 + 4^2 - 2 * 3 * 4 * cos(60)
Evaluate the exponents and the product
z^2 = 9 + 16 - 12
Evaluate the sum and the difference
z^2 = 13
Take the square root of both sides
z = 3.6
Hence, the length of the third side is 3.6 units

2. The Salton Sink in California is approximately 215 feet below sea level. Which of the following best describes the location of the Salton Sink as it relates to sea level?
a –215
b 0
c +215
d +2150
We need to find the best way to represent the numbers.
The score will be best represented by
The depth of the Salton Sink will be best described as .
under par means that it took less strokes than the par of the course to complete the course.
This represented by
The negative sign comes first.
If the score is over par then it took more strikes than the par of the course.
This score will be best represented by
Let, us take the surface sea level as .
So, the depth below the sea level will be negative and above it will be positive.
Hence, the depth of the Salton Sink will be best described as .
