Math Problem Statement

Calculate the area of the following triangle: one side = 6m, another side = 7m, angle between them = 55 degrees.

Solution

To calculate the area of the triangle in the image, we can use the formula for the area of a triangle given two sides and the included angle, which is:

Area=12absin(C)\text{Area} = \frac{1}{2}ab \sin(C)

Where:

  • a=6ma = 6 \, \text{m} (one side)
  • b=7mb = 7 \, \text{m} (the other side)
  • C=55C = 55^\circ (the angle between these sides)

Now, I'll calculate the area using this formula.The area of the triangle is approximately 17.2 square meters, rounded to one decimal place.
