y=3/2x+3 that is the answer
Remember that all of the angles on one side of a straight line
add up to 180 degrees.
Here's how to use that factoid to set it up:
The two angles on the same side of the slanted line add up to 180.
(5k + 20) + (3k + 16) = 180 .
Solve that for 'k'. Then ... Both angles on the right side of
the vertical line also add up to 180. So the answer to the
question is
[ 180 - (3k + 16) ].
Just folding my arms and sitting back and looking at all of that,
I got 110 degrees. Do NOT use that for the answer, but I'll be
curious to see if it's anywhere close.
Answer
A) The range of the morning test scores is less than the range of the afternoon test scores.
Step by step explanation
Let's find range of the morning class
The lowest number = 75
The highest number = 99
The range of the morning class = 99 - 75
The range of the morning class = 24
Let's find the range of the afternoon class.
The lowest number = 67
THe highest number = 96
The range of the afternoon class = 96 - 67
The range of the afternoon class = 29
According to the range.
The answer A) The range of the morning test scores is less than the range of the of afternoon test scores.
Thank you.
In a 30 60 90 triangle, the short side = one half the hypotenuse = 4.5
The middle side = short side * sq root of 3
So, the middle side = 4.5 * sq root of 3 (

When you have a right triangle, you can use the Pythagorean Theorem to find the missing side length. (this can only be used for RIGHT triangles)
Pythagorean Theorem:
a² + b² = c² [c is the hypotenuse, or the longest line]
Since you know b = 8 and c = √73, plug it into the equation
a² + 8² = (√73)²
a² + 64 = 73
a² = 9
a = √9
a = 3
