Answer:
x = 15
Step-by-step explanation:
The sum of the angles in a triangle is 180º
3x + 5x + 4x = 180
Combine like terms
12x = 180
Divide both sides by 12
x = 15
C = 5x
C = 5 * 15
C = 75º
Answer:
The total length of three sides is 62'-1"
Step-by-step explanation:
We know that 1 foot = 12 inches and 1' = 12''
Part 1)
We also know that side 1=15'-7", side 2=20'-4", side 3=26'-2"
To find the total length of three sides sum the three sides
So the total length=side 1+side 2 +side 3
Now we substitute
Total length=15'-7"+20'-4"+26'-2"
Total length=(15'+20'+26')+(7"+4"+2")
Total length=(61')+(13")
Remember that 12"=1'
13"=12"+1"=1'+1"
Substitute again
Total length=(61')+(1'+1")
Total length=(62')+(1")---------> 62'-1"
<u>Therefore the answer is the total length of three sides is 62'-1"</u>
Answer: discrete.
Step-by-step explanation:
Discrete variable
It is a variable whose value is evaluated by counting.
Example: Number of books published in a month.
Continuous variable
It is a variable whose value is evaluated by measuring ( not countable).
Example: Distance: 1.52 m
Since the number of dental visits a randomly chosen person had for the past 5 years is a countable.
here, Variable: Let X =number of dental visits a randomly chosen person had for the past 5 years
So, the random variable described is discrete.
