Answer 1

to find \(x\) solve
\[2x+9+2x+1=90\]

Answer 2

once you have \(x\) you will know all the angles

Answer 3

No....don't do algebra.. Think!
X has to be the biggest angle.

Answer 4

Now which is smaller....2x + 9 or 2x + 1

Obviously 2x + 1 has to be less than 2x + 9 so W is the smallest

Y is in the middle

Answer 5

In a right triangle...the 90 degree has to be the largest angle. Otherwise the angles will add up to more than 180

Answer 6

x = 20 correct

Answer 7

Is it not obvious that 2x + 9 will always be greater than 2x + 1???\
Why bother solving for x?

Answer 8

then idk

Answer 9

2x + 9 = (2x + 1) + 8

2x + 9 is always 8 more than whatever 2x+1 is

Answer 10

-1/2
