Is there supposed to be an equation that follows? Can I see the entire question?
Answer: 8) 42°, 65°, 115° 9) 1.5, 2
Step-by-step explanation:
8) Right off the bat I know that the measure adjacent to 157° is
23°. With both numbers inside the triangle combined, we get
65° meaning the last number is 115 because that'll add up to 180°
9) Considering the smaller triangle has half the length of the bigger triangle
The length of the rest are half the size too.
EF = 1.5
DF = 2
Answer:

Step-by-step explanation:
i don't know if this is correct but you have to divide 16 from 24. sorry if this is wrong im trying to do the best i can.
Given
h(t)=-16t^2+25t+3
assume h(t) is height measured upwards from ground.
Need h(t)=0 for t>0.
solve
<span>h(t)=-16t^2+25t+3=0
</span>use quadratic formula, A=-16, B=25, C=3
t=(-B +/- sqrt(B^2-4AC))/2A
=-25-sqrt(25^2+192)/(-32)
= {-0.11198, 1.6745} seconds
reject negative root, so
time = 1.6745 seconds.
Multiply one side by another
