To answer this question, it's super important that you understand the ratio of sides for special triangles. This triangle in particular, a 45-45-90 triangle, has a ratio between the legs and hypotenuse of 1:1:
Since we are given the value of the hypotenuse, we know that the value of the two sides multiplied by will be 18. Knowing this, we can write out an equation:
u* = 18
u =
<u>Multiply both sides by </u><u> in order to get rid of the root in the denominator:</u>
u =
u =
u = 9
If you'd like me to explain how I got to the answer any further, just ask!

624/27
first you have to know what number that can be subtracted by 62
1. do 27 times 2 equal 54 then you subtract 62 by 54 equal 8 then you put 84 together that will 84 then multiply 27 times 3 = 81 then subtracted by 84
84-81 equal 3
In the calculator the answer is 23.1111111111
Answer:
Look in explanation.
Step-by-step explanation:
1. is the same as
because since there is a negative exponent, you would want to flip the reciprocal and change the negative to positive.
The rest are very similar to this.
