Find the values of x and y in the triangle below.<br> (Please hurry)
NikAS [45]

Answer:

x = 10.4

y = 9

Step-by-step explanation:

Suppose the triangles are similar

x/26 = 8/20 (side lengths must be proportional) cross multiply expressions

20x = 208 divide both sides by 20

x = 10.4

same goes for y

6/(6+y) = 8/20 cross multiply expressions

120 = 8y + 48 subtract 48 from both sides

72 = 8y divide both sides by 8

9 = y

Find the distance between the points<br><br> (1,8) and (-3,8)
Vilka [71]

Answer:

<h2>4 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

From the question we have

d =  \sqrt{ {(1 -  - 3)}^{2} +  ({8 - 8})^{2}  }  \\  =  \sqrt{ ({1 + 3})^{2} } \\  =  \sqrt{ {4}^{2} }  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  =  \sqrt{16}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>4 units</h3>

Hope this helps you
