4.8, I hope this helps you, I answered this earlier. :)
Answer:
c = 50
Step-by-step explanation:
Using the Pythagorean Theorem:
Plug in the values of a = 14, and b = 48
Answer: Choice A) Triangle ABC is similar to triangle ACD by AA
AA stands for Angle Angle. Specifically it means we need 2 pairs of congruent angles between the two triangles in order to prove the triangles similar. Your book might write "AA similarity" instead of simply "AA".
For triangles ABC and ACD, we have the first pair of angles being A = A (angle A shows up twice each in the first slot). The second pair of congruent angles would be the right angles for triangle ABC and ACD, which are angles C and D respectively.
We can't use AAS because we don't know any information about the sides of the triangle.
Answer:
"Acceleration" means any change in the speed or direction of motion ... speeding up, slowing down, or turning. So . . .
-- The distance traveled in a certain time may increase or decrease.
-- The displacement covered in a certain time may increase or decrease.
-- The speed of the object may increase or decrease.
-- The velocity of the object (speed/direction) will change.
Step-by-step explanation:
Blake has 25 CD's.
25 times 3 = 75
75 + 7 = 82
Joel has 82 CD's.
If Joel has twice as many as Mariella, then divide 82 by 2 and you get 41.
Mariella has 41 CD's.
