= x^2 - y^2/6 * 12/(x-y)
= 6x^2 -y^2 * 72/(x-y)
= 6x^2(x-y) -y^2(x-y) * 72
= 6x^3 - 18x^2 -xy^2 + y^3 * 72
= 432x^3 - 1296x^2 -72xy^2 + 72y^3
30 60 90 triangle
ratio of short leg : hypo = x : 2x
given short leg x = 4 ft
so hypo a = 2x = 2 * 4 = 8
answer
a = 8 ft
----------------------------------------------
P.S.
if you need to do by using cos sin tan then
Cos (60) = Adj/Hypo = 4/a
a = 4/cos(60) as you know cos(60) = 1/2
so
a = 4 /(1/2 = 4 * 2/1 = 8
answer: a = 8 ft
7 sweets is the answerrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
Answer:
124.71
Step-by-step explanation:
V=1
/4h√a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
a,b,c= base sides
h= height
V=1
/4(8)√(6)^4+2(6x6)^2+2(6x6)^2﹣(6)^4+2(6x6)^2﹣(6)^4
V= 124.71
Answer:
1) In right triangle ABC with <A = 90, the ratio for sinB= 5/13. 2) Given ... a) sin (40) = 32/CA b) Cos(50) = 32/ CA ... In triangle RST, angle R is a right angle. If TR = 6 . and ... Determine the length of AC to the nearest 10th.
