<h3>
Answer: Both angles are equal to 45 degrees</h3>
===========================================================
Explanation:
When using the SSS congruence rule, we can prove that triangle DCA is congruent to triangle BCA.
Since the triangles are congruent, the corresponding pieces angle DCA and angle BCA are equal in measure (if they weren't, then the triangles wouldn't be congruent).
Recall that any square has four right angles, ie all angles are 90 degrees each. Angle DCB is cut in half to get 90/2 = 45.
The angles DCA and DCB are 45 degrees each.
Answer:
$18,112.45 (nearest cent)
Step-by-step explanation:
Let y = value of the boat
Let x = the number of years
If the boat depreciates in value by 15% each year, then each year that goes by, it is worth 85% of the previous year's value (since 100 - 15 = 85)
85% = 85/100 = 0.85
Therefore, the equation is: ![y = 92000 \times 0.85^x](https://tex.z-dn.net/?f=y%20%3D%2092000%20%5Ctimes%200.85%5Ex)
So, when x = 10:
![\implies y = 92000 \times 0.85^{10}=18112.45](https://tex.z-dn.net/?f=%5Cimplies%20y%20%3D%2092000%20%5Ctimes%200.85%5E%7B10%7D%3D18112.45)
