Answer:
Explanation:
You just need to find the ratio of lengths of one of the sides and apply it to the unknown side:
72
24
=
3
This means that the triangle on the right has sides that are 3 times the length of the smaller triangle.
x
7
=
3

Answer:
x = 36
Step-by-step explanation:
Remark
This can be done as a proportion. A proportion consists of 2 ratios which means it has 4 parts. If you know three of them, you can solve for the 4th.
We can use the following proportion
42/14 = x / 12 Notice that both ratios have tops and bottoms that use corresponding parts. Cross Multiply
14*x = 42 * 12 Combine the right
14x = 504 Divide by 14
x = 504/14
x = 36

Is the correct mixed number
It really depends what you're understanding or how the problem is set up.
Answer:
a
Step-by-step explanation:
When a triangle is obtuse, the length of c^2 is bigger than the combined lengths of a^2 and b^2.
a^2+b^2<c^2
"A" is the best answer.
I hope this helps!
