A scalene triangle has the lengths 6, 11, and 12. Keyla uses the law of cosines to find the measure of the largest angle. Comple

ss7ja [257]

Answer:

$Y\approx 84^\circ $(to the nearest angle)$

Step-by-step explanation:

The lengths of the sides of the scalene triangle are 6, 11, and 12.

We want to use the law of cosines to find the largest angle.

Note that the largest angle is always opposite the largest side.

Therefore:

$1. 12^2 = 11^2 + 6^2-2(11)(6)\cos(Y) \\\\2. 144 = 121 + 36-(132)\cos(Y) \\\\3. 144 = 157 - (132)\cos(Y) \\\\4. -13 = -(132)\cos(Y)\\\\\\5. \cos(Y) = \dfrac{-13}{-132} \\\\6. Y = \arccos \left ( \dfrac{13}{132}\right)\\\\7. Y=84.35^\circ\\\\8. Y\approx 84^\circ $(to the nearest angle)$

The largest angle is 84 degrees to the nearest angle.

How many persons are in the line? Ashley is in the line to buy a ticket. There are twice as many people in front of Ashley as th

Klio2033 [76]

Answer:

I am pretty sure there are 10 people in line.

Since Ashley is the seventh person in line, we can deduce that there are 6 people in front of her.

Since the amount of people in front of her is "twice as many people as there are behind her," we can divide the value of the people in front of her in half to get the value of people behind her.

6/2 is 3, so there are 3 people behind Ashley.

Now, lets add the amount of people in front of Ashley to the amount of people behind her. 3 + 6 = 9, and since Ashley is also in the line, we should add 1 to the sum.

9 + 1 = 10, so there are 10 people in the line.

The angle of depression is 30 degrees from the bottom of the boat to a

OlgaM077 [116]

Given :

The angle of depression is 30 degrees from the bottom of the boat to a

deep sea diver a the depth of 120 ft.

To Find :

The distance x the diver must swim up to the boat to the nearest foot.

Solution :

Let, distance between diver and boat is x.

So,

$sin\ 30^o=\dfrac{h}{x}\\\\x = \dfrac{120}{\dfrac{1}{2}}\\\\x = 240 \ ft$

Therefore, distance the diver must swim up to the boat to the nearest foot is 240 foot.

Hence, this is the required solution.
