Finch species living on the Galapagos Islands exhibit a variety of beak types that work for different foods. Finches that eat seeds and plant parts have beaks of the shorter, thicker variety while finches that eat insects and other small organisms have thin,
pointed beaks. Over the last century the percentages of finch species have drastically changed on one island. At one time, Finch 4
comprised over 75% of the finch population on the island. Today, Finch 4 is virtually extinct. What conclusion can we reach about
the conditions on this island?

answer: 12

step-by-step explanation:

(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
