D. find an equation for the line tangent to the curve at the point defined by the given value of t.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

47 - 90 = 43

43 - 180 = x

x = 137

(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

if e is the midpoint of bd, then bd is 14.
