x=8+√59 or x=8−√59

Step-by-step explanation:

For this equation: a=1, b=-16, c=5

1x2+−16x+5=0

Step 1: Use quadratic formula with a=1, b=-16, c=5.

x=

−b±√b2−4ac

2a

x=

−(−16)±√(−16)2−4(1)(5)

2(1)

x=

16±√236

2

x=8+√59 or x=8−√59

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
