1) (x,y) = no solution

2) x=-2y

-2y-y = 9

-3y = 9

y = -3

x = -2(-3)

x = 6

(x,y) = (6,-3)

4 taken away from one fourth of 'p' is 10 ?

pentagon [3]

I'm assuming we have to solve for "p" here...

By making an equation, we will get...

(p/4)-4=10

Add four on both sides...
(p/4)=14
Remove parentheses and multiply by four on both sides.
p=56

---|----------------

For the 69° angle, h is the opposite leg, and 20 ft is the hypotenuse.

sin A = opp/hyp

sin 69° = h/20

h = 20 * sin 69°

h = 18.67
