Mathematics

HACTEHA [7]3 years ago

Answer:

A: The chord is perpendicular to the diameter

Proof:

CE=DE (definition of bisector)

Center O, so OC and OD are radii.

OC=OD.

OE=OE.

OCE=ODE  (SSS)

angle OEC = angle OED  (corresponding parts)

angle OEC  and angle OED are supplementary

So angle OEC and angle OED are both right angles.

CD is perpendicular to OE

CD is perpendicular to AB

Jesse surveyed 3/4 of the students at her school. Of those surveyed, 2/3 participate in school club or sports team. According to
OLga [1]
3/4 * 2/3 = > 6/12 ; Then you simplify it and the answer will be 1/2. Therefore the fraction of the students who participated in a school club/sports team is 1/2.

Find the missing length of the triangle. *
Amanda [17]

Answer:

50 ft

Step-by-step explanation:

This is the pythagorean theorem, so you should use the formula...

a squared + b squared = c squared

Then substitute in the numbers... (remember, a and b are the legs, and c is the hypotenuse)

14 squared + 48 squared = c squared

14 squared = 14 x 14 = 196

Now we have 196 + 48 squared = c squared

48 squared = 48 x 48 = 2,304

Now we have 196 + 2,304 = c squared

Add them together - 2,304 + 196 = 2,500

Now we have 2,500 = c squared

We find the square root of 2,500 which is 50

You should now have 50 = c

That is your answer. Don't forget to add units.

50 ft is your hypotenuse (c)
