Answer:

∠AB=9

Step-by-step explanation:

<em>the pyagrothyes therom= </em> $a^{2}$ <em>+</em> $b^{2}$ <em>=</em> $c^{2}$

<em>to find ∠AB we need to find the height of the triangle.</em>

<em>replace the variables:</em>

$a^{2}$ <em>+</em> $6^{2}$ <em>=</em> $9^{2}$

<em>=</em> $9^{2}$ <em>-</em> $6^{2}$ <em>=</em> $a^{2}$

<em>simplify:</em>

<em>81-36=</em> $\sqrt{45}$

<em>now we solve for ∠AB</em>

<em>replace the variables:</em>

$6^{2}$ <em>+</em> $\sqrt{45}$ <em>=</em> $c^{2}$

<em>simplify:</em>

<em>36+45=</em> $\sqrt{81}$

$\sqrt{81}$ <em>=9</em>

I hope this helps you!!

Jason and Alison are hiking in the woods when they spot a rare owl in a tree. Jason stops and measures an angle of elevation of

Shalnov [3]

Answer:

$Owl= 67.14ft$

Step-by-step explanation:

<em>See comment for complete question.</em>

The given information is represented in the attached figure.

First convert 22°8'6'' and 30° 40’ 30” to degrees

$22^{\circ} 8'6'' = 22 + \frac{8}{60} + \frac{6}{3600}$

$22^{\circ} 8'6'' = 22.135^{\circ}$

$30^{\circ} 40'30'' = 30 + \frac{40}{60} + \frac{30}{3600}$

$30^{\circ} 40'30'' = 30.675^{\circ}$

Considering Jason's position:

$tan(22.135^{\circ}) = \frac{H}{x + 48}$

Where x = distance between the tree and Alison

Make H the subject

$H = (x + 48)tan(22.135^{\circ})$

Considering Alison's position

$tan(30.675^{\circ}) = \frac{H}{x}$

Make H the subject

$H = xtan(30.675^{\circ})$

$H = H$

$(x + 48)tan(22.135^{\circ}) = xtan(30.675^{\circ})$

$(x + 48) *0.4068 = x* 0.5932$

Open bracket

$x *0.4068 + 48 *0.4068 = 0.5932x$

$0.4068x + 19.5264 = 0.5932x$

Collect Like Terms

$-0.5932x+0.4068x = -19.5264$

$-0.1864x = -19.5264$

$0.1864x = 19.5264$

Make x the subject

$x = \frac{19.5264}{0.1864}$

$x = 104.76$

Substitute 104.76 for x in $H = xtan(30.675^{\circ})$

$H = 104.76 * tan(30.675^{\circ})$

$H = 104.76 * 0.5932$

$H = 62.14$

The above represents the height of the tree.

The height of the owl is:

$Owl= H + 5$

$Owl= 62.14 + 5$

$Owl= 67.14ft$
