Answer:
2.98 centavos
Step-by-step explanation:
Divide 140.06 by 47
Angle E = 180 -45 -63 = 72 degrees
Using the Law of Sines
FD / sine (E) = ED / sine (63)
3.8 / 0.95106 = ED / 0.89101
side DE = 3.8 * .89101 / .95106
side DE =

Answer:
O4) x = y
Step-by-step explanation:
I took this before
Use pythagorean theorem to find the bottom side of the left triangle.
12^2+b^2=15^2
144+b^2= 225
b^2= 81
b=9
you will then subtract 9 from 25 to get 16
area from the triangle on the right
A=(1/2)16*12
A= 96 in^2
then for the triangle on the right
A= (1/2)12*9
A= 54 in^2
then add the two areas together
Total Area= 150 in^2
