The answer is 31.4 just do 3.14 times 5 times 2
If I remember correctly judging from the 30 in the top left all you would have to is subtract 180 which is the angle of a straight line and subtract it from the 30 and it would be 150
Answer:
Step-by-step explanation:
we know that
In a rectangle, the two diagonals are congruent and each diagonal bisects the other
so
----> equation A
-----> equation B
step 1
Find the value of x
solve equation A
substitute the given values
solve for x
step 2
Find the value of KE
substitute the value of x
Remember that
-----> by each diagonal bisects the other
therefore
The chemical formula for water is H2<span>O which means that every </span>molecule<span> of water has 2 </span>atoms<span> of hydrogen (H) and one </span>atom<span> of oxygen (O). Here comes the key part. From the Periodic Table of Elements, one sees that one mole of hydrogen </span>atoms weighs <span>1 gram while one mole of oxygen </span>atoms<span> weighs 16 grams.</span>
Multiple 16 by 1 and then divide by 8 which makes 2.
Multiply 36 by 1 and then divide by 9 which makes 4.
