Find the value of x, which makes the area of this triangle equal 72. Choose one answer. a. x=4.6875 b. x=9.375 c. x=6 d. x=10.5
(1/2)(2x - 3)(8) = 72 is your base equation Then, (4)(2x - 3) = 72 -> 2x - 3 = 18 -> 2x = 21 x = 10.5
Oh, BTW, that first equation is from (1/2)(h)(b) = A
thanks! :) I understand!
