Which segment of the triangle will give you the height of your peak? Write the equation for the proportion that will allow you t

Novosadov [1.4K]

The segment that will give the height of the peak is the segment that is located from the right angle to the peak.
To find the height, we can use the fact that we have two similar triangles.
We are going to define a variable.
We have:
x: height of the peak.
For similar triangles, we have the following relationship:
$\frac{x}{20} = \frac{6}{3}$
From here, we clear the height of the peak
Answer:
the equation for the proportion that will allow you to find the height of your peak is:
$\frac{x}{20} = \frac{6}{3}$

1. Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 36. How old is each sister?

jonny [76]

Something times 2 plus itself equals 36.

2 times 12 = 24
24 plus 12 = 36

2 x 12 +12 =36
or
36 divided by 3
or
12x = 36
by dividing 12 into 36, x =3

Because 36 is a whole and even number, Kim's sister's age should be even as well. The age would be multiply itself 3 times. So Kim's sister is 12 yr old, and Kim's age is 24 years old.
