For the following question, find the area of the triangle. give the answer to the nearest tenth. The drawing may not be to scale
Alina [70]

Answer:

Option A

10.5 m²

Step-by-step explanation:

The area of a triangle is half the product of its base by its height.

A = 0.5bh

Where b is the base and h is the height.

In this triangle b = 6.1 m.

The height of this triangle is a line perpendicular to its base that goes to the vertex opposite the base.

We do not know this length. But this line h divides the triangle into two rectangular triangles.

So for these two triangles the angle that is opposite to the height h is: 47 °

Therefore we know that senx is defined as:

senx =\frac{opposite side}{hypotenuse}

Where:

Opposite side = h

hypotenuse = 4.7 m

x = 47

Sin(47) = \frac{h}{4.7}\\\\h = (sin47)(4.7)\\\\h = 3.437

Finally, the area is:

A = 0.5(3.437)(6.1)\\\\A = 10.5m^2
