The angles of a triangle are 2x, 3x, and 4x degrees. Find the value of x.

$2x+3x+4x=180$ would be the equation

You could refine it to make $9x=180$

Divide both sides by 9 $9x/9=180/9$

This gives you $x=20$

Hope this helps!

What is the perpendicular slope intercept form?

In-s [12.5K]

Answer:

y = -1/2x + 2.5

Step-by-step explanation:

- slope of a perpendicular line is the negative reciprocal of the original slope (2 in this case) so y = -1/2 x + c

- to find c we substitute the values from the given point into the equation

(0) = -1/2*(5) + c

- rearrange and calculate and you'll get c = 5/2 or 2.5

- replace the value of c and now you've got y = -1/2x + 2.5
