What are you trying to find? Area or perimeter?

The answer would be 60 because you do based times height which equals the area

Answer:

$x=1174\ feet$

Step-by-step explanation:

<u>Right Triangle </u>

It's a special type of triangle where one of its internal angles is 90°. The basic trigonometric formulas apply to relate lengths and angles. If h is the opposite side to the angle \theta, and x is the adjacent side of the same angle, then

$\displaystyle tan\theta =\frac{h}{x}$

Or, equivalently

$\displaystyle x =\frac{h}{tan\theta}$

The helicopter, ground and the two soldiers form two right triangles, as shown in the image below. Let's call x1 the distance from soldier 1 to the point O, then

$\displaystyle x_1 =\frac{h}{tan53^o}$

$\displaystyle x_1 =\frac{1200}{tan53^o}$

$x_1=904 \ feet$

Now for x2, the distance from soldier 2 to the point O

$\displaystyle x_2 =\frac{1200}{tan30^o}$

$x_2=2078\ feet$

The distance between the soldiers is

$x=2078\ feet-904\ feet$

$\boxed{x=1174\ feet}$

Can you help me with this problem please?

Answer:

PR = 2*36 = 72

SU = (1/2)54 = 27

RS = 36

Step-by-step explanation:

By the Midpoint Theorem, the argent that connects midpoints of the sides of a triangle equals half the parallel side. That said,

PR is the full side that corresponds to midpoint segment TU. Therefore it's twice the distance of TU.
SU is the midpoint segment that corresponds to fill side PQ and therefore half the distance.
RS is half the the length of PR since S is the midpoint.

So of the guestion is -5 <-2 then i add 7 to both sides what and how would I do it

Dafna1 [17]

-5+7=2, and -2+7=5 so now it would be 2<5! :-)
