Answer:
Sorry not 100% but it is definitely 18 or 6.
90% sure its 18 though
Step-by-step explanation:
Answer:
1022.25 square feet
Step-by-step explanation:
The length and width sum to half the perimeter, so the length is ...
P/2 -W = length = 134/2 -23.5 = 43.5 . . . . feet
The area is the product of length and width, so is ...
A = LW = (43.5 ft)(23.5 ft) = 1022.25 ft^2
The area of the garden is 1022.25 ft^2.
Answer:
hmm sorry
Step-by-step explanation:
Answer:
49 x^4 - 4 = 0
(7 x^2 - 2) (7 x^2 + 2) = 0
Only the first term will have real roots
7 x^2 = 2
x = (2 / 7)^1/2 = .535 or -.535
Step-by-step explanation:
we use the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
a, b, c being the sides, A, B, C being the opposing angles of the sides.
and remember, the sum of all angles in a triangle is 180°.
so,
JL/sin(90) = KL/sin(72)
JL/1 = KL/sin(72)
KL = JL × sin(72) = 10 × 0.951056516... =
= 9.51056516... ≈ 10
JK/sin(L) = JL/sin(90) = JL
JK = JL × sin(L)
angle L = 180 - 90 - 72 = 18°
JK = JL × sin(18) = 10 × 0.309016994... =
= 3.09016994... ≈ 3
