Answer:
Part 1) 
Part 2) 
Part 3) 
Step-by-step explanation:
we know that
EB=ED+DB
ED=DB -----> given problem
Substitute the given values and solve for x




<em>Find the value of ED</em>

substitute the value of x

<em>Find the value of DB</em>
Remember that
ED=DB
therefore

<em>Find the value of EB</em>
EB=ED+DB

Ashton has saved: 60% of $120=(60/100)*$120=(60*$120)/100=$72
Ashton need to buy the bike=$120-$72=$48
He needs to buy the bike=$48
Answer:
Step-by-step explanation:
The given triangle is a right angle triangle.
The distance between the first bed and the bird watcher on the ground represents the opposite side of the right angle triangle.
The distance between the birdwatcher and the second bird is 47 feet. This represents the hypotenuse of the right angle triangle. To determine the angle of depression, x degrees, we would apply the Sine trigonometric ratio which is expressed as
Sin θ = opposite side/hypotenuse
Sin x = 34/47 = 0.723
x = Sin^-1(0.723)
x = 46.3 degrees to the nearest tenth.
Answer:
Non proportional
Step-by-step explanation:
Oddly enough, when y=-1/3, the value of y is -1/3.
When x = -1/3, the value of y is
.. y = 3*(-1/3) -2
.. = -1 -2
.. = -3
When x = -1/3, the value of y is -3.
