Work out the area of triangle give your answer to 1 decimal place ​
forsale [732]

<u>Given</u>:

Given that the triangle.

Let the length of the side a be 10 cm.

Let the length of the side b be 13 cm.

Let the measure of ∠C is 105°

We need to determine the area of the triangle.

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

A=\frac{1}{2} a b \ sin \ c

Substituting a = 10, b = 13 and ∠C = 105°, we get;

A=\frac{1}{2}(10)(13) \ sin \ 105

Simplifying, we get;

A=\frac{1}{2}(10)(13)(0.966)

A=\frac{1}{2}(125.58)

A=62.79 \ cm^2

Rounding off to 1 decimal place, we have;

A=62.8 \ cm^2

Thus, the area of the triangle is 62.8 cm²
