Answer:
204 miles
Step-by-step explanation:
All I did was divide 143 by 3.5 and got 40.85(I rounded it), then I multiplied 40.85 by 5 and got 204 (I also rounded that if it doesn't need to be rounded then the real answer would be 204.25)
You should be more clear with this.
Are you asking for 4% of the number 4 or 4 multiplied by the percent 4.
I'm going with 4% of 4 since that makes more sense.
In any case, 4% of 4 is 0.16
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
