X, Y and Z form the vertices of a triangle, where ∠ YXZ = 68°, XY = 7.3m and XZ = 8.3m. Calculate the area of the triangle. Round your answer to 1 DP.

Area = 28.2m²

Step-by-step explanation: The triangle YXZ is shown in the figure below.

Area of a triangle is calculated by the formula:

According to the figure, the base of this triangle is b = 8.3m.

Height is a perpendicular line created from one side and intersecting the opposite angle.

To determine the height, use trigonometric relations to angle 68:

h = 7.3*sin(68)

h = 7.3*0.93

h = 6.8

Now, area of triangle YXZ is

A = 28.2

Area of triangle YXZ is 28.2m².

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
