This is a rectangle, meaning that all angles are right angles and all sides opposite to one another have equal length.
Since the length of CD is 24, the length of AB must also be 24.
Angle B is a right angle because this is a rectangle.
See anything? I'll you a hint. We have a right triangle with only one missing value.
What do we use to solve for missing lengths in a right triangle? The Pythagorean theorem, of course!

The length of c (the hypotenuse) is 26.
The length of a (one leg) is 24.
The length of b is unknown and we want to find it.


Subtract 576 by both sides.

Take square root of both sides.

The length of the missing leg is 10, meaning that the length of BD is 10.
This is what you should be needing. Enjoy!
Are u like in 9th grade omg
Answer:
65
Step-by-step explanation:
All the angles in a right triangle add up to 180
plug in what we know and we get
90+25+x=180
115+x=180
x=65
Answer:
y = 70 degrees
x = 11
Step-by-step explanation:
The side opposite x + 2 is equivalent so they will both be equal to 13.
To get the meaning of x, simply subtract 2 from 13 giving you x = 11.
Y is across from corner C, which is 70 degrees. These angles are equivalent to each other, meaning that angle y is also 70 degrees.
Hope this helps you :)
