I need help with this ASAP so could you please help me

The area of a triangle is: A = 23.2 cm²

Step-by-step explanation:

Given

a = 10 cm

b = 9 cm

The angle ∠C = 31°

To determine

Area of the triangle

Using the formula to determine the area of the triangle

Area = 1/2bc sin C

substituting a = 10, b = 9, and m∠C = 31°

Area = 1/2 × 9 × 10 × sin 31°

Area = 1/2(90) sin 31°

Area = 45 × sin 31°

Area = 23.2 cm²

Therefore, the area of a triangle is: A = 23.2 cm²

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
