The walls are vertical so the angle opposite X would be a right angle which is 90 degrees.
X would be 180 - 90 - 35 = 55 degrees
X and 2y - 5 are complementary angles which add together to equal 90:
2y - 5 + 55 = 90
Simplify:
2y +50 = 90
Subtract 50 from both sides:
2y = 40
Divide both sides by 2:
y = 20
Answer:
f ( x ) = [ x ] + 1
Step-by-step explanation:
Answer
1. - x < -y
Step by step explanation
When we multiply, add and divide the value remains the same.
But when you change the sign, the inequality direction will be > in this case, otherwise that is not ture.
For instance,
2 < 3
-2 < -3 is not true.
Because -2 is greater than -3
Hope this will help you.
Thank you. :)

Answer:
Yes, it is a right triangle.
Step-by-step explanation:
a^2+b^2=c^2
The longest side is the hypotenuse so c^2 would be 90.
72^2+54^2=90^2
72 and 54 can be either a or b.
Solve for all exponents: 5184+2916=8100.
That equation is true, so the triangle is a right triangle.
