So I’m thinking of this as two triangles. So I would do 16x8/2 which equals 64 and 10x6/2 which equals 30. So my guess is that the area is 94in^2. Hope this helps you out!

Answer:

y = 5/3x + 48

Step-by-step explanation:

y2 - y1 / x2 - x1

28 - 8 / -12 - (-24)

20 / 12

5/3

y = 5/3x + b

8 = 5/3(-24) + b

8 = -40 + b

48 = b

Scale of model is 1 inch represent how many feet in real life
8inch=scale
30 feet=real
8:30=4:15=2:7.5=1:3.75
the one we can se taht matches is D
4 inches=15 feet

Answer:

Corey stepped back 59.71 feet

Step-by-step explanation:

Right Triangles

They are a special type of triangle where one of its internal angles is 90°. The basic trigonometric equations stand in this type of triangles. If x is the adjacent leg of a given angle $\theta$ , and y is the opposite leg to the same angle, then :

$\displaystyle tan\theta=\frac{y}{x}$

We can solve for x to get

$\displaystyle x=\frac{y}{tan\theta}$

Corey estimates the height of the tree to be 80 feet. This means we know y=80 and $\theta=68^o$ . Let's find the horizontal distance at which Corey is looking at the bald eagle:
