15 cm
18 cm

The image of the triangle is missing, so i have attached it.

x = 26.2 cm

Step-by-step explanation:

To find the value of x, we will use cosine rule;

x² = 15² + 18² - 2(15 × 18)cos105

x² = 225 + 324 - 540(-0.2558)

x² = 549 + 138.132

x² = 687.132

x ≈ 26.2 cm

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
