Find the area of the triangles round to the tenth. Show steps please!
amm1812

Answer:

\large\boxed{A=89.6}

Step-by-step explanation:

It's the right triangle. The formula of an area of a right triangle:

A=\dfrac{leg\cdit leg}{2}

We have:

leg=x\\leg=16\\\text{and the angle}\ \alpha=55^o

Use tangent:

tangent=\dfrac{opposite}{adjacent}

opposite=16,\ adjacent=x

\tan55^o\approx1.4281

Substitute:

\dfrac{16}{x}=1.4281        <em>convert the decimal to the fraction</em>

\dfrac{16}{x}=\dfrac{14281}{10000}          <em>cross multiply</em>

14281x=160000            <em>divide both sides by 14281</em>

x=\dfrac{160000}{14281}

x\approx11.2

Calculate the area:

A=\dfrac{(16)(11.2)}{2}=89.6
