Step-by-step explanation:
The Pythagorean Theorem is:

Where a is the hypotenuse and b and c are the legs.
The missing side lenght is one of the legs, then you must solve for one of them. Therefore, this is:

MEASURE OF ANGLE:
Keep the identities on mind:



Susbstitute values, then:






Answer:
Step-by-step explanation:
Internal dimensions of the box will be smaller considering the thickness of the wood:
- 21 - 1 = 20 cm
- 11 - 1 = 10 cm
- 7 - 0.5 = 6.5 cm (open top)
<u>The volume is now:</u>
The answer is 5 feet.
1/4 = 1.25/x
x = 4•1.25
x = 5
There's all sorts of angle pair like if the vertical or supp or same side and alots more but idk wut pairs u r looking for a pic would really help here!
Next time plz post a photo please and thank you have a nice day
Answer:
1/40
Step-by-step explanation:
A bag contains 5 blue, 3 red, and 8 green marbles
You have (5+3+8=16) marbles
P(red 1) = red/total = 3/16
You do not replace it
A bag contains 5 blue, 2 red, and 8 green marbles
You have (5+2+8=15) marbles
P(red 2nd) = red/total = 2/15
P(red 1, red 2) = P (red 1)* P (red 2) = 3/16 * 2/15
=1/40
