Determine the area of the blue triangle below. Round your answer to
the nearest tenth.

A = 68.9 in²

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = ab sinC ( a, b are 2 sides and C the angle between them )

Here a = 12, b = 15 and C = 50° , then

A = × 12 × 15 × sin50°

   = 6 × 15 × sin50°

   = 90 × sin50° ≈ 68.9 in² ( to the nearest tenth )
