Match the side lengths and angles to the areas of the triangles.
**Topic: Calculating Areas of Triangles Using Side Lengths and Angles** In this exercise, you are tasked with matching the side lengths and angles of different triangles to their respective areas. Use the formula for the area of a triangle when you know two sides and the included angle: \[ \text{Area} = \frac{1}{2} \times a \times b \times \sin(C) \] Here are the descriptions of four triangles with their side lengths and angles: 1. A triangle with \( a = 5 \, \text{m} \), \( b = 6 \, \text{m} \), and an included angle of \( 135^\circ \). 2. A triangle with \( a = 5 \, \text{m} \), \( b = 8 \, \text{m} \), and an included angle of \( 27^\circ \). 3. A triangle with \( a = 6 \, \text{m} \), \( b = 7 \, \text{m} \), and an included angle of \( 40^\circ \). 4. A triangle with \( a = 9 \, \text{m} \), \( b = 5 \, \text{m} \), and an included angle of \( 65^\circ \). **Areas to Match:** a. \( 10.607 \, \text{m}^2 \) b. \( 9.080 \, \text{m}^2 \) c. \( 13.499 \, \text{m}^2 \) d. \( 20.392 \, \text{m}^2 \) To find the correct match, calculate the area for each triangle using the given values and compare with the options provided.
