Answer:

169.6

Step-by-step explanation:

We can use trig to find the missing side (sin specifically).  sin(x)=opposite/hypotenuse.  where x is the angle.  VWX is 20 degrees.  The side opposite to that angle is VX or 58.  We dont know the hypotenuse.  If we were to substitute values into sin(x)=opposite/hypotenuse, we would get sin(20)=58/hypotenuse.  sin(20) in the calculator is 0.342020143...  so we can rewrite the equation as 0.342020143=58/hypotenuse.  Lets call the hypotenuse h.  If we multiply h on both sides, we can try to find what h is equal to.  0.342020143h=58.  Now we can divide 0.342020143 on both sides to isolate h.  h=169.58... or if we round it, we get 169.6

On a vocabulary list within a study guide, definitions should be written
Lana71 [14]

Solution:

In a vocabulary list ,within a study guide, if we are defining something

It should never be written in abbreviated form because some words are difficult to understand in abbreviated form and chances of getting confused are higher while reading.

It is better if we start writing Definition in

Arranging in alphabetical order and then writing in complete sentences.

But writing in complete sentences of any vocabulary must be first priority.

mina [271]
The answer is about 12.5 (when rounded to the nearest 10th). 

This can be found using the distance formula between each point. One distance is 5, one is \sqrt{2} and one is \sqrt{37}. Added together gives you the answer above.

16 divided by 1/8 minus 1
elena-s [515]
16 divided by 1/8 - 1

first, you would make 16 into a fraction, making the new equation 16/1 divided by 1/8 -1. you'd then flip 1/8 to 8/1 making the new equation 16 divided by 8 - 1. 16 divided by 8 is 2, and 2 - 1 = 1.

the answer is 1.

In 2/3 of a hour, workers had installed 2/5 of a foor. At the rate,what fraction of the flooring is finished after 1 hour?
padilas [110]
3/5 or 60%.

2/3 hour is 40 minutes, so 1/3 is 20 minutes.

40 minutes have passed and 2/5 of the progress on the floor is complete. In 20 minutes, 1/5 of the work is complete. Add 20 minutes to 40 minutes to get 60 minutes, or an hour.
Because of this, we need to add the progress of 20 minutes and 40 minutes. 1/5+2/5=3/5.
