Use the diagram below to solve for x and y.

Mrac [35]

Answer:

Option A. x=30,y=42

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

Triangles ABC and ZYX have three congruent interior angles

therefore

Triangles are similar

step 1

Find the value of x

$\frac{ZY}{AB}=\frac{ZX}{AC}$

substitute the values

$\frac{20}{x}=\frac{12}{18}$

$x=20*18/12=30\ units$

step 2

Find the value of y

$\frac{ZY}{AB}=\frac{XY}{CB}$

substitute the values

$\frac{20}{30}=\frac{28}{y}$

$y=30*28/20=42\ units$

Write the equation of the line that passes<br> through the points (3, 1) and (-2, 6).

tia_tia [17]

Answer:

Equation is Y=mx+c (that's how I know it, it may differ)

Step-by-step explanation:

First get the slope which is M and you just gotta do the second y - the first y from the brackets and divide them by the second x - the first x

6-1 /-2-3 = 5/-5

= -1

So now u gotta find c, C= Y-mx

And u have got two brackets, which have an x and y, and u now have m.

Pick one of the brackets like (-2,6) and put them in the equation so it will be : C =6+1*-2

So C =4

The equation now is : Y = - 1x + 4

A sprinkler sprays water in a circular area up to 30 feet. A radius reduction screw lets people reduce the radius by up to 25%.

tankabanditka [31]

Answer: $1590.63\ ft^2$

Step-by-step explanation:

Given

The sprinkler can water the area up to $30\ ft$ i.e. $30\ ft$ is the radius

If the screw leads to a reduction of 25% in radius, then the new radius is

$r'=(1-0.25)r\\r'=0.75r\\r'=22.5\ ft$

So, the area corresponding to this radius

$\Rightarrow \pi (22.5)^2\\\Rightarrow 1590.63\ ft^2$

Thus, the maximum area that can be covered is $1590.63\ ft^2$
