Answer:
66.8421% decrease
Step-by-step explanation:
Yes: by definition, two adjacent angles have the same vertex, a side in common and don't overlap.
So, if two angles share the vertex and a side, but they overlap, they are not adjacent.
For example, consider the origin, the x and y axes, and the bisector of the first quadrant
Define angle between the x axis and the bisector, and angle between the x axis and the y axis. So, and have the same vertex (the origin) and one side in common (the x axis), but they do overlap, and are not adjacent.
We have a trapezoid and a triangle
area of trapezoid=(base1+base2) times 1/2height
area of traingle=1/2 base times height
triangle
base=18
height=12
area=1/2 times 12 times 18=108
trapezoid
to find height we do
17=12+height
subtrac 12
5=height
so
base1=14
base2=18
height=5
area=(14+18) times 1/2 times 5
area=32 times 1/2 times 5
area=80
total area=area of trapezoid+area of triangle
total area=80+108
total area=188 mm^2
Selection C is appropriate.
Probably, the function only usefully describes the height between the time it is thrown (x=0) and the time it lands (x=5).
_____
Conceivably, a function can be written that would describe height before it is thrown and after it hits the ground (as after it bounces, for example). In that case, one might be interested for the domain of "all real numbers" or at least "all real numbers representing the time during which the object was in existence."
Answer:
Step-by-step explanation:
Given
The attached triangle
Required
Find x and y
From the triangle; the angle sign in x and 52 means;
3y and 15 are congruent sides
So:
