Find the area of the following triangle. Show each of the math steps that you use to find the area. Then explain how to go about
Diano4ka-milaya [45]

Semi perimeter:-

\\ \rm\rightarrowtail s=\dfrac{a+b+c}{2}

\\ \rm\rightarrowtail s=\dfrac{1.8+2.4+3}{2}

\\ \rm\rightarrowtail s=\dfrac{7.2}{2}=3.6cm

Apply heron s formula

Area:-

\\ \rm\rightarrowtail \sqrt{s(s-a)(s-b)(s-c)}

\\ \rm\rightarrowtail \sqrt{3.6(3.6-1.8)(3.6-3)(3.6-2.4)}

\\ \rm\rightarrowtail \sqrt{3.6(1.8)(0.6)(1.2)}

\\ \rm\rightarrowtail \sqrt{4.6656}

\\ \rm\rightarrowtail 2.16cm^2

A plane descends 1000 ft while flying<br> 2.7 mi. What is the angle of descent?
Murrr4er [49]

Answer:

4.02°

Step-by-step explanation:

The angle of descent can be obtained using trigonometry ;

Since we have a right angled triangle ;

Let's use the relation:

Sin θ = opposite / hypotenus

Hypotenus = 2.7 miles

1 mile = 5280 feets

2.7 miles = (2.7 * 5280) = 14256 feets

Sin θ = 1000 / 14256

Sin θ = 0.0701459

θ = sin^-1(0.0701459)

θ = 4.0223674
