Answer:
The solution in point form is (9,7) and the equation would be x+9, y=7
Step-by-step explanation:
By using moving the -4y to the right side and by flipping the signs you can turn the equation -x-4y=-37 into x=37-4y.
With this new equation you can use the substitution method and replace the x in -2x-5y=-53 with 37-4y, making it look like this: -2(37-4y)-5y=-53.
Then you solve for y getting y=7.
With the value of y, you can plug that into the equation x=37-4y so it will look like x=37-4(7)
Then you solve for x getting x=9
And with that you get the point (9,7)

Answer:
(A) 120°
Step-by-step explanation:
m∠P=x
m∠S=2x
m∠Q=x
m∠R=2x
Sum of the angles in trapezoid is 360°.
x+x+2x+2x=360
6x=360
x=60°
m∠R=2x=2*60=120
