True or False The area of a triangle equals one-half the product of the lengths of two of its sides times the sine of their included angle.
To find: Whether the given statement is true or false: The area of a triangle equals one–half the product of the lengths of two of its sides times the sine of their included angle.
Answer to Problem 4AYU
Solution:
True.
Explanation of Solution
Given:
The area of a triangle equals one–half the product of the lengths of two of its sides times the sine of their included angle.
Calculation:
If two sides and and the included angle are known in a triangle, then the area is found using the formula
Hence, the statement “The area of a triangle equals one–half the product of the lengths of two of its sides times the sine of their included angle” is true.
