Answer:
x = 102
Step-by-step explanation:
Isosceles triangles have equal angles opposite equal sides. There are two 39° angles in this triangle (opposite the 3.3 sides), so the third one is ...
x° = 180° -2(39°)
x° = 102°
_____
<em>Additional comment</em>
The triangle is "overspecified", meaning more measures are provided than are necessary to completely describe the triangle. As is often the case in such situations, the measures provided are sufficiently inconsistent that two different "right" answers are possible, depending on how you work the problem. The first attachment shows the solution above.
The second attachment shows the solution you might get by using the Law of Cosines. Note that x=101 in this case.
From the given problem above, the correct answer would be the last option since it stated that a number which is X is increased by five or added by five and then the sum is then squared. Therefore, it is option D. (X+5)^2.
The value of the car after 5 years would be $23914.85
<u>Explanation:</u>
Given:
Worth of the new car = $50,000
Every 5 years the value depreciates by 1/2
i.e., every 5 years the value depreciates by 50%
So, we can say that every year the value depreciates by 10%
The worth of the car after 7 years would be

where,
W is the depreciated value
C is the current value
D is the depreciation rate
t is the time
Substituting the value in the equation we get:

Therefore, the value of the car after 5 years would be $23914.85
