Triangle abc has sides that are 5. 6 and 7. triangle def has sides that are 3.75 x and 5.25. find the middle side of triangle def then find the perimeter of triangle def

hi, i am not sure about this one but i think its d,

hope this !

(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

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.
