<u>Answer:</u>
Perimeter = 20 units
x = 120°
<u>Step-by-step explanation:</u>
We are given a triangle ABC with known side lengths for all three sides and an inscribed circle.
We are to find the perimeter of triangle ABC and the value of x.
Perimeter of triangle ABC = 2 + 2 + 5 + 5 + 3 + 3 = 20 units
The kite shape at the end is a quadrilateral which has a sum of angles of 360 degrees.
Two out of four angles are right angles and one is 60 so we can find the value of x.
x = 360 - (90 + 90 + 60) = 120°

Answer:
<em>$2,025.78 </em>
Step-by-step explanation:
I = Prt ⇒ P = 
2.25% = 0.0225
P = 45.58 ÷ ( 0.0225 × 1 ) ≈ <em>$2,025.78</em>
