Apebble is tossed from the top of a cliff. the pebble's height in feet is given by y(t) = -16t2 + 6t + 200, where t is the time in seconds. its horizontal distance in feet from the base of the cliff is given by d(t) = 5t.
how far will the pebble be from the base of the cliff when it hits the ground? round to the nearest foot. ft use a number only.

(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
