Question

#3. Find the area of the triangle. Round to 2 decimal places. Thanks.

Answer 1

C

Explanation:

The area (A) of the triangle is calculated using

A =
`(1)/(2)` ab sinC

where a, b are the 2 sides and C is the angle between them

here a = 6, b = 2 and C = 80°, hence

A = 0.5 × 6 × 2 × sin80° = 5.91 cm² → C

Answer 2

Multiply 6*2 and get 12. Now divide by 2 and get 6. I think it’s c
