Could someone me with this one as well. i swear this is my last question-

73.4

Step-by-step explanation:

The shaded area can be split into two shapes: a triangle and a sector.

The area of the triangle can be found using the SAS formula:

A = ½ ab sin C

A = ½ (5 cm) (5 cm) (sin 80°)

A = 12.31 cm²

The sector angle is 360° − 80° = 280°.  The area is:

A = (θ / 360) πr²

A = (280 / 360) π (5 cm)²

A = 61.09 cm²

So the total area is:

A = 12.31 cm² + 61.09 cm²

A = 73.4 cm²

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)

the answer is the third / last answer
