Assume Chad is standing up straight.
Chad, the shadow of Chad, and the line from the top of Chad's head to the end of the shadow form a right triangle.
Chad and the shadow are the two legs of the right triangle, the line form the top of Chad's heat to the end of the shadow is the hypotenuse.
the angle facing Chad is 23 degree.
One leg length is given. To find out other leg (the height of Chad), use tangent.
tan23=x/14.3
x=tan23*14.3
use a calculator, x≈6.07
this answer makes sense because 6 feet is about the height of a man.
Plug in -4 into x and 10into y
10+20=10
30 does not equal 10
The answer is no
Angle XZY *may be written as YZX* is vertical to angle VZU
UZY *may be written as YZY* is a linear pair to angle VZU
Answer:
yes it is.
Step-by-step explanation:
12(2x - 8) = 15
12(2x) - 12(8) = 15
24x - 96 = 15
<u> + 96 + 96</u>
<u>24x</u> = <u>111</u>
24 24
x = 4.625
