Because the angles are supplementary, they add to 180 degrees.

I solved this by dividing $\frac{180}{6}$ which gives me 30 degrees.

multiply 30 by 5 gives you 150.

and 30 + 150 = 180

3x+2=198 Solve it as Soon as possible!

Let's solve for x ~

$3x + 2 = 198$

$3x = 198 - 2$

$3x = 196$

$\boxed{ \boxed{x = \dfrac{196}{3} } \: \: or \: \: \boxed{ x = 65.33}}$

Can someone please explain how I do this. My teacher is kinda useless.

givi [52]

when the altitude is drawn from the vertex of the right angle of a right triangle to its hypotenuse, the altitude equals the product of the two segments of the hypotenuse.
(w+9)²=8*18=144
w+9=12 or w+9=-12
w=3 (discard the negative number)

use the same method, z=√(9*11)=3√11

next, you can use the Pythagorean theorem to find x and y.
x=√(9²+99)=√180=6√5
y=√(11²+99)=√220=2√55
