This falls under geometry. The two labeled angles are congruent, which means the line segment between them (AD in the image) is a bisector of the angle at vertex A. Use the angle bisector theorem, which says that
![\dfrac{BD}{DC}=\dfrac{AB}{AC}\iff\dfrac{12}{(5+9x)-12}=\dfrac{15}{25}](https://tex.z-dn.net/?f=%5Cdfrac%7BBD%7D%7BDC%7D%3D%5Cdfrac%7BAB%7D%7BAC%7D%5Ciff%5Cdfrac%7B12%7D%7B%285%2B9x%29-12%7D%3D%5Cdfrac%7B15%7D%7B25%7D)

Answer:
Velocity = 59 feet/second
Step-by-step explanation:
h(t) = 15 + 60t – 16t2
Time t = 1 second
Let's substitute time into the equation to get the distance
h(t) = 15+60(1)-16(1)²
h(t) = 15 + 60 - 16
h(t) = 59 feet
Speed or velocity = distance/time
Distance = 59 feet
Time = 1 second
Velocity = 59/1
Velocity = 59 feet/s

Answer:
0.000025
Step-by-step explanation:
the difference between225-180=45
so the percentage= 45×100/100
=0.45%
as the instruction say=0.45%/180
=0.0045/180
=45/1800000
=0.000025
