Given :-
- 12 workers can do a piece of work in 20 days .
To Find :-
- How many workers should be added to complete the work in 16 days ?
Solution :-
According to the question ,
→ In 20days 12 workers can do a piece of work.
→ In 1day 12*20 workers can do that work
( Less days , more workers )
→ In 16 days 12*20/16 = 15 workers can do the work.
So 15 -12 = 3 workers should be added to complete the work.
<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>3 </u><u>.</u>

Answer:
One
Step-by-step explanation:
First, we need to check a triangle with these sides <em>is</em> possible. Since 4 plus 5 is 9, and 9 is less than 10, we can make a triangle with these sides.
To answer the question, we can only make one unique triangle. Why? They give us three lengths and a triangle has three sides.
<em>However</em>, if they are counting a triangle in different positions the answer will be greater. Since it would just be the same triangle, I am going with the answer of only one.
OptionC is the answer..!!
Hope this helps you!!!

Answer:
angle 1 = 61
Step-by-step explanation:
This is a little hard to explain without drawing a diagram .. but if you extend live vs until it intersects line p, you can form a triangle. Using corresponding angles rule for parallel lines, you have the exterior angle of the triangle with line p is 130, meaning the interior angle is 50 (angles on a straight line add to 180). Similarly, the interior angle of the triangle at S is 180 -111 = 69. So the two interior angles add to 50+ 69 = 119. Lastly, angle 1 is equal to the third interior angle of this triangle (due to vertically opposite angles being equal), so since angles in a triangle add to 180, angle 1 = 180 -119 = 61.
