The answer is C . -7r^2 + 12r -8
Answer:
<u>108°</u>
Step-by-step explanation:
Formula :
<u>Degree Measure = Arc length / radius x 180/π</u>
Solving :
Degree Measure = 3π/5 x 180/π
Degree Measure = 3 x 36
Degree Measure = <u>108°</u>
Answer:
$15.17
Step-by-step explanation:
divide 34 by 32 = 1.0625. and divide it by the 7%= $15.17
we are given that
angle(ACF)=90
angle(ACB)=61
sum of all angles along any line is 180
so, we get
angle(ACF)+angle(ACD)=180
we can plug value
90+angle(ACD)=180
angle(ACD)=90
now, we can use formula
angle(ACD)=angle(ACB)+angle(BCD)
now, we can plug values
and we get
90=61+angle(BCD)
90-61=61-61+angle(BCD)
angle(BCD)=29................Answer
The roots to this equation i s either positive or negative five
