tan(46°) = 250 / d rearrange
d = 250 / tan(46°) = about 241 ft
Let us check the angle opposite the longest side.....we can use the Law of Cosines and the cosine inverse
900 = 100 + 576 - 2(100)(576)cosx
acos [ 900 - 100 - 576] / [ -2(10)(24) ] = x = about 117. 82°
So......it is obtuse
The side = sqrt(200) m ..... and the diagonal = sqrt(2) * sqrt(200) = sqrt(400) = 20 m
tan (7°) = h / 5 where h is the height....rearrange
h = 5 tan(7°) = about 0.614 mi = 1 mile [rounded to the nearest mile]
What's the question ????
(x^2-4x+3) + (3x^2-3x-5)
Line these up like this :
x^2 - 4x + 3
+ [3x^2 - 3x - 5 ] Now, add as you normally would
4x ^2 - 7x - 2 and that's your result
15000 / 3 = 5000 frs per day x 5 days = 25000 frs
1 + 1/3 L = 4/3 L and there are 10 dL in each L......so we have 10 *4/3 = 40/3 dL
And 2 + 1/2 dL = 5/2 dL
So....the number of cakes she can bake =
(40 / 3 ) / (5 / 2) =
(40 / 3) * (2 / 5) =
80 / 15 =
About 5 whole cakes
12 + h = c
9 + a = b
