Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence. the angle
Mekhanik [1.2K]

The height of the​ tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.

<h3>What is right angle triangle property?</h3>

In a right angle triangle, the ratio of the opposite side to the base side is equal to the tangent angle between them.

\tan\theta=\dfrac{b}{a}

Here, (b) is the opposite side, (a) is the base side.

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence.

The angle of elevation of the tree from one position on a flat path from the tree is

H=40^o

From a second position,

I=60\rm\; ft

Farther along this path it is,

b=30^o

Let the distance between tree and first position is x. Thus, from the trigonometry,

\tan 40=\dfrac{h}{x}\\h=x\tan 40             ....1

The distance between tree and second position is (x+60) ft. Thus, again from the trigonometry,

\tan 30=\dfrac{h}{x+60}\\h=(x+60)\tan 40               ......2

Compare the equation 1 and 2,

x\tan (40)=(x+60)\tan 30\\0.839x=0.577x+34.64\\0.839x-0.577x=34.64\\x=\dfrac{34.64}{0.262}\\x=132.25\rm\; ft

Put this value in equation 1 as,

h=(132.25)\times \tan40\\h\approx111\rm\;ft

Thus, the height of the​ tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.

NO ONE CAN SOLVE THIS, NEITHER CAN YOU :::By what percent will a fraction change if its numerator is decreased by 10% and its de
Veseljchak [2.6K]

Answer:

9/5

Explanation:

original fraction : x/y

new fraction = .9x/(.5y)

= 9x/5y

(9x/5y) / (x/y)

= 9x/5y * y/x

= 9/5

= 1.8

so it increased by 80%

e.g suppose we had 100/200 or 1/2

new fraction = 90/100 or 9/10

new ratio = (9/10) / (1/2)

= 9/5

Which triangles are congruent according to the sas criterion?.
julia-pushkina [17]

<u>SAS Criterion:</u> If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.

From the diagram you can see that:

<A ≅ <F ≅ <P

AB ≅ GF ≅ PQ

AC ≅ FE ≅ PR

This means that ΔABC, ΔFGE, and ΔPQR are congruent.
