Answer:
43.3 square inches
Step-by-step explanation:
Given two sides <em>a</em> and <em>b</em> and the angle α between them, the area of the triangle can be computed as ...
A = (1/2)ab·sin(α)
Putting the given values into the formula gives ...
A = (1/2)(14.1 in)(7.8 in)sin(52°) ≈ 43.3 in²
The area of the triangle is about 43.3 square inches.

And replacing the info given we got:
The amount of each of the 6 payments will be $41.50
Step-by-step explanation:
Given,
Cost of bike including taxes = $349
Down payment = $100
Amount left to pay = Cost of bike - Down payment
Amount left to pay = 349 - 100
Amount left to pay = $249
She agrees to pay in 6 equal payments, therefore, we will divide the total amount to pay by 6.
Amount to pay for one month =
Amount to pay for one month =
The amount of each of the 6 payments will be $41.50
