Which lines are parallel? justify your answer.
lines a and b are parallel because their corresponding angles are congruent.
lines a and b are parallel because their same side exterior angles are congruent.
lines e and f are parallel because their corresponding angles are congruent.
lines e and f are parallel because their same side exterior angles are supplementary.

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

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
