Find the values of x, y, and z. The diagram is not to scale.

Kruka [31]

we know that

The sum of the internal angles in the triangle must be $180$ degrees

see the attached figure with letters to better understand the problem

Step $1$

Find the measure of the angle x

In the triangle ABC

$63\°+36\°+x\°=180\°$

solve for x

$99\°+x\°=180\°$

$x\°=180\°-99\°$

$x=81\°$

therefore

the answer Part a) is

the measure of angle x is $81\°$

Step $2$

Find the measure of the angle z

we know that

$x+z=180\°$ --------> by supplementary angles

substitute the value of x

$81\°+z=180\°$

$z=180\°-81\°$

$z=99\°$

therefore

the answer Part b) is

the measure of angle z is $99\°$

Step $3$

Find the measure of the angle y

In the triangle ACD

$13\°+z\°+y\°=180\°$

solve for y

$13\°+99\°+y\°=180\°$

$112\°+y\°=180\°$

$y\°=180\°-112\°$

$y\°=68\°$

therefore

the answer Part c) is

the measure of angle y is $68\°$

If there are 210 student and only 46 students get a permission slip to holiday hills what is the percent of the student who did

Eduardwww [97]

First you would find the difference of 210 and 46, so 210-46=164.
Then you will divide the solution by the total number of students, so
164 divided by 210.
164/210= about .780 or 78%

What is the equation of a line in slope intercept form that passes through (-2,2) and is perpendicular to the graph of y=1/2x-3.

tangare [24]

The answer is y = -2x-2

To find the slope of a line perpendicular to your equation, you just need to find the reciprocal. This just means flip the signs (change positive to negative, or negative to positive) and flip the numerator and denominator. So if you have 1/4 as your slope, the perpendicular slope would be -4/1 (which is just negative 4).

I changed the “b” from -3 to -2 so it would run through the points (-2, 2).

I hope this helps :)
