What is the value of x in the figure shown below?

HELP RIGHT NOW PLEASE!!!!!!!!!!!! What is the value of x?
barxatty [35]

Answer:

x = 34

Step-by-step explanation:

Add together all three angles because together they equal 180 degrees

x + 12 + x + 100 = 180         Combine like terms

2x + 112 = 180

     - 112   - 112                   Subtract 112 from both sides

2x = 68                              Divide both sides by 2

x = 34

A submarine dives at a constant speed of 10 m/s at a diving angle measured from the vertical
valina [46]

Answer:

155.3 m

Step-by-step explanation:

<u>We have:</u>

θ: is the angle measured from the vertical = 75 °

v = is the speed of the submarine = 10 m/s

t = 1 min

The deep of the front end of the submarine at the end of a 1-minute drive is given by the following ratio:

cos (\theta) = \frac{x}{d}  

<u>Where:</u>

d: is the distance traveled by the submarine in 1 minute

x: is the deep to find

The distance, d, is:

d = v*t = 10 \frac{m}{s}* 1 min * \frac{60 s}{1 min} = 600 m

Now, the deep is:

cos (75) = \frac{x}{600}  

x = cos(75)*600 = 155.3 m

Therefore, the deep of the front end of the submarine at the end of a 1-minute drive is 155.3 m.

I hope it helps you!
