Assume that the area of the parallelogram abcd is 120 square inches and that the area of triangle abec is 15 square inches. length of ab is 12 sq. in.
what is the area of triangle ade?

im sorry but no. i just need to answer for 50 poonts oof

correct

step-by-step explanation:

i think it is 18

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
