6 0

Answer:

Okay so, we know that Theta =10°

Opposite=7ft

Adjacent= x ft

And then

Tan 10=7/x

Hence

X=7/tan10

X=39.69897 39. 7 ft

new car is purchased for 17300 dollars. The value of the car depreciates at 9.25% per year. What will the value of the car be, t
mojhsa [17]

Answer:

$4034

Step-by-step explanation:

The new value is given by

A=P(1-i)^{n} where A is the final value, P is initial value, i is depreciation rate in decimal, n is duration in years. Substituting 17300 for P amd 15 for n then

A=17300(1-0.0925)^{15}=4034.0902388653093042610864428203245692614\approx 4034

The perimeter of this triangle is 25 units. An angle bisector divides one side of the triangle into lengths of 2 and 3. Find the
grin007 [14]

Answer:

   8 and 12

Step-by-step explanation:

Sides on one side of the angle bisector are proportional to those on the other side. In the attached figure, that means

  AC/AB = CD/BD = 2/3

The perimeter is the sum of the side lengths, so is ...

  25 = AB + BC + AC

  25 = AB + 5 + (2/3)AB . . . . . . substituting AC = 2/3·AB. BC = 2+3 = 5.

  20 = 5/3·AB

  12 = AB

  AC = 2/3·12 = 8

_____

<em>Alternate solution</em>

The sum of ratio units is 2+3 = 5, so each one must stand for 25/5 = 5 units of length.

That is, the total of lengths on one side of the angle bisector (AC+CD) is 2·5 = 10 units, and the total of lengths on the other side (AB+BD) is 3·5 = 15 units. Since 2 of the 10 units are in the segment being divided (CD), the other 8 must be in that side of the triangle (AC).

Likewise, 3 of the 15 units are in the segment being divided (BD), so the other 12 units are in that side of the triangle (AB).

The remaining sides of the triangle are AB=12 and AC=8.
