Answer:
x = -6 ±sqrt(251)
Step-by-step explanation:
3(x+6)^2=753
Divide each side by 3
3/3(x+6)^2=753/3
(x+6)^2=251
Take the square root of each side
sqrt((x+6)^2)=±sqrt(251)
x+6 = ±sqrt(251)
Subtract 6 from each side
x+6-6 = -6 ±sqrt(251)
x = -6 ±sqrt(251)
There are the same because 4/8 is rudeced to 1/2
Answer: x=40 y=140
Step-by-step explanation:
To work out x:
The angles in a triangle always add up to 180.
You already have one angle which is 50 the bottom left angle is a right angle and right angles always equal 90. To work out x, do 50+90=140 then do 180-140=40.
To work out y:
Angles on a straight also add up to 180.
So as you have figured out what x is (40) you would take it away from 180 to give you y.
180-40=140
Hope this helps :)
