Answer=B 4.8
We have a right triangle in the drawing so for the altitude we can use the pythagorean theorem. It's as follows...
a²+b²=c² (where a and b are the side lengths and c is the hypothenuse)
Lets input in the data that we have.
11²+b²=12²
simplify
121+b²=144
subtract 121 from both sides
b²=23
To solve for the missing side/altitude we just need to find the square root of 23
b=√23
b=4.79 or 4.8
Answer=B
So for you can answering this your exercise question right,correct ,so you need learning the pythagora's theorem what about say ????
- in case of a right triangle the sum of the length squared of the two sides equal the length of hypotenuse squared
hope this will help you answering right your exercise question
Answer:
24x+3
Step-by-step explanation:
This question wants you to reverse the operations that occurred.
Start with 12 stamps.
Divide this number by 3/4. This represents Carla giving 1/4 of the stamps to Thomas.
Multiply this number by 2. This represents Jim giving half of the stamps to Carla.
Multiply this number by 2. This represents John giving half of his stamps to Jim.
John started out with
64 stamps.
Pi=3.14, So 86 x 3.14= [ 270.04]
