-Before the experiment there was 530.2g of salt in the beaker.

-During the experiment each student removed 47.36g of salt from the beaker:

47.36g x 3 students= 142.08g of salt

Now you have to find how much grams of salt was left in the beaker at the end of the beaker:

Total amount-Amount removed by students: 530.2g-142.08g=388.12g of salt at the end of the experiment.

One of the same-side exterior angles formed by two lines and a transversal is equal to 1/6 of the right angle and is 11 times smaller than the other angle. Then the lines are parallel

<h3><u>Solution:</u></h3>

Given that, One of the same-side exterior angles formed by two lines and a transversal is equal to 1/6 of the right angle and is 11 times smaller than the other angle.

We have to prove that the lines are parallel.

If they are parallel, sum of the described angles should be equal to 180 as they are same side exterior angles.

Now, the 1st angle will be 1/6 of right angle is given as:

$\begin{array}{l}{\rightarrow 1^{\text {st }} \text { angle }=\frac{1}{6} \times 90} \\\\ {\rightarrow 1^{\text {st }} \text { angle }=15 \text { degrees }}\end{array}$
