One of the kinds special triangles you learn about are the Pythagorean triples. These are right triangles with sides in certain ratios. One of them has sides in the ratios 3:4:5.
More generally, this triangle has sides in the ratio 3x:4x:5x
In your triangle, the ratio 8:10 corresponds to 4x:5x with x=2. Therefore, the remaining side is 3x with x=2, so
b=6

Answer:
answer is 3 11/12
Step-by-step explanation:
1 4/6 =10/6
2 1/4=9/4
when adding fractions that are do not share a common denominatour you have to find a common multiple
which in this case is 12
so 9/4 timesed the top and the bottom by 3 gives you 27/12
and 10/6 timesed the top and bottom by 2 gives you 20/12 and then you add the the nominators which is 20+27 which then gives you 47/12 and then to change it back to mixed fraction you will get 3 (wholes) and 11/12 (fraction)

What is the value of c?
Answers
the answer is c=8
hope that helps lolol
Answer: c=8
Step-by-step explanation: All three angles in a triangle add up to 180 degrees so 9c+66+42=180. First add 66 and 42 which is 108, so now you have 9c+108=180. Then subtract 108 from both sides to get 9c=72. Finally, divide each side by 9 to isolate c and you get c=8

for the first question you put the right answer, well done!
for the second question:
the missing side is 14.1 ft.
c²= a²+b²
16.7² = x² +8.9²
278.89= x²+79.21
x²=278.89-79.21= 199.68
we want to find x not x² so we square root x² and that gives us the value for x
x=Square root of 199.68

In a park for 6 people the ticket cost $39. How many dollar does it cost for 9 people
Answers
$ 58.50
Step-by-step explanation:
because 39 Divided by 6 is 6.5 and 6.5 × 9 it's 58 50
$58.50
•EXPLANATION•
The first thing you have to do is divide 39 by 6 to see how much it would cost for 1 person. For 1 person it cost $6.50 then you multiply by 9 because you are trying to figure out how much it cost for 9 people not 1. You will get $58.50.

Explain how you could use a number line to determine the number that is 8 less than 3 what is the number
Answers
Answer and explanation:
8 less than 3 is subtracting 8 from 3:
3-8
If we wish to find this using the number line, we would need to find the value given if negative eight and positive three are added. Our answer would likely fall on the negative/left side of the number line since the value 3 has less to give than what is required -8( use the analogy of oranges available and oranges given/required)
3-8= -5
We count from 0 to the left -5

Answer:
x=5
Step-by-step explanation:
so it would be 2(5) since 5 is x and that would be 10+y=10.

10+0=10.
