The angle of depression is congruent to your angle of elevation (the squirrel's line of sight. These are opposite angles. You use SOH CAH TOA to find the missing information because this forms a right triangle. SO you are really trying to solve for the hypotenuse here. 
You are given the  "side" opposite the angle. souse the SOH part Sine=opposite/hypotenuse
so when you plug in the information you get this equation:
sin(50)=14/x
divide both sides by sin(50) and you should get 
a hypotenuse of approx. 18.3

The distance from the owl to the squirrel would be found by using the law of sins/co-sins

Cos (known angle) = adjacent leg / hypotenuse ( distance wanted)

cos(50) = 14 / x

x = 14 / cos50

x = 21.78 feet

 The problem doesn't say if the answer should be rounded or not. You may have to round the answer if needed.

Write the slope intercept form that satisfies the following conditions
Olin [163]

y = 3x - 13

Step-by-step explanation:

The line will have the same slope as the given line, which is m = 3. Therefore, the equation of the line in its slope-intercept form is

y = 3x + b

Next we need to solve for b by plugging in the coordinates of the given point:

(-4) = 3(3) + b \Rightarrow b = -13

So the equation of the line is

y = 3x - 13

If y=80,when x=32 find x when y=100
Bess [88]
Y        X
80     32
100    x'

80x' = 100*32
80x' = 3200
x' = 3200/80
x' = 320/8
x' = 40

Matt is canoeing on Lake opeongo fighting a headwind. it takes him 2 hours to get to the lake 4km away. on the way back it takes
Mariana [72]

So Matt is canoeing on a Lake.

It took him 2 hours to get to the lake 4 kilometers away.

On the way back it takes him 90 minutes.

Now, lets say that he is canoeing at 'u' miles per hour and lets assume that the speed of the wind is 'v' miles per hour.

While he sails in opposite to the wind net speed is given by u-v.

Using the relation between distance, time, and speed we get:

u-v=\frac{4}{2} =2 kilometers per hour so we get,

u-v=2 ..............(equation 1)

Now when he sails along the wind, the net speed is given by u+v

Now, again use the same relation as stated above we get:

u+v=\frac{4}{1.5} =2.6 (here we have converted 90 minutes into hours \frac{90}{60} =1.5)

u+v=2.6 ..............(equation 2)

Solving equation 1 and 2 we get:

u=2.3 , putting the value of 'u' in equation 1 we get v=2.6-2.3=0.3.

So the speed at which Matt is canoeing is 'u' that is 2.3 kilometers per hour and the wind is flowing at 0.3 kilometers per hour.

So Matt can canoe at 2.3 kilometers per hour without wind. And wind is slowing him down by 0.3 kilometer per hour.

NEED HELP ASAP!! WILL MARK BRAINLIEST!!
Nookie1986 [14]

Step-by-step explanation:

The Chord Intersection Theorem:

If 2 chords of a circle are AB and CD and they intersect at E, then

AE * EB = CE * ED.

Problem.

Two Chords AB and CD intersect  at E.  If AE =  2cm , EB = 4 and CE = 2.5 cm, find the length of ED.

By the above theorem : 2 * 4 = 2.5 * ED

ED = (2 * 4) / 2.5

= 3.2 cm.

is this what u wanted??????????
