Answer:
efd is 52 and cfd is 43
Explanation:
180-85 bc its a straight line
you get 95, now you can make an equation
6x - 20 +2x + 19 = 95. simplify it
8x - 1 = 95, add1 to isolate the variable
8x = 96 (divide both sides to isolate variable) is equal to 12
subsitute 12 into both equations.
efd = 52 and cfd = 43
