Question

Which triangle’s area would be calculated using the trigonometric area formula?

Triangle E F D is shown. The length of E F is 10, the length of D F is 7, and the length of D E is 12.


Triangle Q R P is shown. The length of Q R is 5 and the length of R P is 6. Angle Q R P is 40 degrees.


Triangle A B C is shown. The length of A B is 4 and the length of B C is 5. Angle B C A is 25 degrees.


Triangle X Y Z is shown. The length of Y Z is 4. Angle Z X Y is 29 degrees and angle X Y Z is 110 degrees.

Answer: the second option aka B

Step-by-step explanation: The other person explained it and I'm just here to tell you they gave the correct and answer for edge 2020.

Answer 2

Triangle Q R P is shown. The length of Q R is 5 and the length of R P is 6. Angle Q R P is 40 degrees.

Explanation:

The trigonometric formula refers the two sides length of the triangle and it also consists of included angle to find out the area

A =
`(1)/(2)` ab sin C

QPR contains two sides and the included angle

XYZ has one side and the two angles

DEF has only three sides

And, the ABC contains two sides but does not have the included angle

Based on the explanation above, the correct option is B
