We know angle BAD= CBA so we can do:
42+105 + x = 180
x = 180-105-42
x=33
Hope this helps!! :)
Answer:
4.5^3 because we know v=lwh. since its a cube l, w, h will all equal 4.5
Let the number of runs made on the home run be x, then for the <span>two 3-run home runs, we have 2x
Let the number of runs made in each hit be y, then for the 4 hits that each scored 2 runs, we have 4y.
Thus the algebraic expression to model the total score is 2x + 4y.
Because, there are 3 runs per home run, then x = 3 and because there are 2 runs per hit, then y = 2.
Therefore, the total score is given by 2(3) + 4(2) = 6 + 8 = 14.
