You would divide 4 from each side and that means that you would get 10/4 and that doesn’t go in evenly so you know it will be a decimal. You then solve the division and get 0.25 so that means that x=0.25

No can I please have brainliest because I have you an explanation?

How do I solve this, it's not 10
guapka [62]

Answer:

26.7

Step-by-step explanation:

This is the answer because 26.7/20 = (16+26.7)/32

When two triangles are similar, it means their sides are also proportional. The reason why it is not ten is because you need to add 10 to 16 to the large triangle as well, which no longer makes it proportional.

To solve, you create a formula.

(16+x)/32=x/20

Multiply both sides by 32 to get rid of the 32 in the left side.

16+x=32x/20

Multiply both sides by 20 to get rid of the 20 right side.

320+20x=32x

-20x on both sides to get all the variables on one side and all the nukbers on the other.

320=12x

Divide both sides by 12 to get x by itself

x=26.66667

To estimate the height of a totem pole, Jorge uses a small square of plastic. He holds the square up to his eyes and walks backw
Ghella [55]

The height of the pole is 6.50 meters

<h3>How to calculate the height?</h3>

To calculate the height of the pole, we will use of the following equivalent ratios.

By Pythagoras theorem, we have:

x ^2 = 2^2 + 3^2\\\\x ^2 = 4 + 9\\\\x = \sqrt{13}

So, we have:

h = \dfrac{\sqrt{13}^2 }{2} \\\\h = \dfrac{13}{2}\\\\h = 6.5

Hence, the height of the pole is 6.50 meters

Find the measure of the missing value in the
kumpel [21]

Answer:

12.6

Step-by-step explanation:

The two left sides have lengths, so this allows you to establish the ratio of the lengths of the sides of the triangles,

left triangle : right triangle

ratio = 25 : 17.5

The bottom sides are also in the same ratio.

ratio = 18 : w

Write a proportion by setting the ratios equal and solve for w.

25/17.5 = 18/w

Cross multiply.

25w = 17.5 * 18

25w = 315

w = 12.6

Answer: 12.6
