(1/4)*(4*x+15) = 24 // - 24
(1/4)*(4*x+15)-24 = 0
1/4*(4*x+15)-24 = 0
1/4*(4*x+15)-24 = 0
x-81/4 = 0
x-81/4 = 0
x-81/4 = 0 // + 81/4
x = 81/4
x = 81/4
hope I helped
A = 1/2 bh can be written as
A = bh/2.
2A = (bh/2)(2)
2A = bh
Divide both sides by h to find b.
2A/h = b
Done.
Draw a perpendicular segment from point C to the midpoint of AB. Using the trig sine function sin 80 = x/6 which gives 5.91 for the perpendicular segment. Using the formula A=1/2bh, A= 1/2 x5.91x2sqrt 2 A= 8.4
