For this problem, we are going to use the <em>law of sines</em>, which states:

In this case, we have an angle and two sides, and we are trying to look for the third side. First, we have to find the angle which corresponds with the second side,  . Then, we can find the third side. Using the law of sines, we can find:
. Then, we can find the third side. Using the law of sines, we can find:

We can use this to solve for  :
:


Now, we can find  :
:

Using this, we can find  :
:

Answer:
$3937.50
Step-by-step explanation:
315,000 * 1.25% = 315,000 * 1.25/100 = 3,150*1.25 = 3937.5
 
        
             
        
        
        
Answer:
 Isosceles trapezoid
Step-by-step explanation:
-An isosceles trapezoid is also sometimes called a convex quadrilateral.
-It properties include:
- A line of symmetry can often bisects a pair of opposite sides.
- It has to obtuse alternating with each other after which a pair of acute angles alternate with each other i.e 80°, 80°,100°,100°
- It has a trapezoidal shape which by definition has a two pair of parallel sides.
- The angles on it's base or ceiling are equal hence the name Isosceles Trapezoid.
