A boat is heading towards a lighthouse, where Chee is watching from a vertical distance of 105 feet above the water. Chee measures an angle of depression to the
boat at point A to be 11°. At some later time, Chee takes another measurement and
finds the angle of depression to the boat (now at point B) to be 28°. Find the
distance from point A to point B. Round your answer to the nearest tenth of a foot if
necessary

step-by-step explanation:

d. 344.22

(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
