If you multiplied 2x3 you get the area of half of the whole figure. But to get the other portion I subtracted 4-3 and got 1, the I multiplied 5x1 and got 5. so the answer is 11in^2.

Answer:

Step-by-step explanation:

From the given figure, divide the proportion in such a way that we have two rectangles, then Area of one rectangle=l{\times}b=2{\times}3=6 sq inches

and area of the another triangle=l{\times}b=5{\times}1=5 sq units

Therefore, Area of the irregular figure= Area of rectangle 1 + arae of rectangle 2

=6+5=11 sq inches

Thus, area of the irregular figure= 11 sq inches.

If

Given:

In a right angle triangle θ is an acute angle and \tan\theta =\dfrac{3}{5}.

To find:

The value of \cos \theta.

Solution:

In a right angle triangle,

\tan \theta=\dfrac{Perpendicular}{Base}

We have,

\tan\theta =\dfrac{3}{5}

It means the ratio of perpendicular to base is 3:5. Let 3x be the perpendicular and 5x be the base.

By using Pythagoras theorem,

Hypotenuse=\sqrt{Perpendicular^2+base^2}

Hypotenuse=\sqrt{(3x)^2+(5x)^2}

Hypotenuse=\sqrt{9x^2+25x^2}

Hypotenuse=\sqrt{34x^2}

Hypotenuse=x\sqrt{34}

In a right angle triangle,

\cos \theta=\dfrac{Base}{Hypotenuse}

\cos \theta=\dfrac{5x}{x\sqrt{34}}

\cos \theta=\dfrac{5}{\sqrt{34}}

Therefore, the value of \cos \theta is \dfrac{5}{\sqrt{34}}.
