Can someone help me figure out the length of this perpendicular bisector its for geometry. Angle A is 90 degrees, DB is 27 and DC is 3. I need to find out AD.

The triangles are similar. what is the value of x? enter your answer in the box. x = two right triangles. the larger right triangle is labeled x on the longer leg, 12 on the shorter leg and 20 on the hypotenuse. the smaller triangle is labeled 4 on the longer leg, 3 on the shorter leg, and 5 on the hypotenuse.

An angle that measures between 90 and 180° is called a(,

What is the result of the following division?
