Answer:
- The side opposite ∠L is NM.
- The side opposite ∠N is ML.
- The hypotenuse is LN.
Step-by-step explanation:
Even a crude drawing can be helpful as you sort this out. (See attached.)
In general, the side opposite an angle <u>will not</u> have the letter of the angle in its name. Similarly, a side adjacent to the angle <u>will</u> have the angle letter in its name.
The statements that apply are ...
- The side opposite ∠L is NM.
- The side opposite ∠N is ML.
- The hypotenuse is LN. (opposite right angle M)
Since the area is 120 ft^2, and we know the length of the room is 15 ft, we can calculate the width.
120/15 = 8
To find the perimeter, we use the following formula
2l + 2w = P
2 (15) + 2 (8) = 46 ft
137,426.9 is 140,000 when rounded to 2 sig figs
The two-way table is attached.
We know that 63 people took the survey, and 22 of them were left-handed. This means that 63-22=41 of them are right handed.
Out of the 63 total, 37 are left brain dominant; this means that 63-37=26 are right brain dominant.
Of the 26 that are right brain dominant, 21 are right handed; this means 26-21=5 are left handed.
Of the 22 left-handed people, 5 are right brain dominant; this means 22-5 = 17 are left brain dominant.
Of the 37 left brain dominant people, 17 are left handed; this means 37-17=20 are right handed.
