Answer:

  28 m

Step-by-step explanation:

The longer side can be found using the Law of Cosines. The semi-diagonals are of length 12 and 20 m, and the angle between them facing the long side is 180° -60° = 120°.

  c^2 = a^2 +b^2 -2ab·cos(C)

  c^2 = 12^2 +20^2 -2·12·20·cos(120°) = 144 +400 +240 = 784

  c = √784 = 28

The longer side is 28 meters.

Convert y=9 from rectangular to polar form
Crazy boy [7]

Answer:

r = 9/sin Ф or r = 9 csc Ф

Step-by-step explanation:

The polar form is represented as:

x = r cos Ф and

y = r sin Ф

We are given:

y = 9

Putting value in y = r sin Ф

9 = r sin Ф

=> r = 9/sin Ф

1/sin Ф = csc Ф

or, r = 9 csc Ф

a group raised $276 for its favorite charity. this is 23% of the amount it hopes to raise. how much money does the group want to
OverLord2011 [107]

Answer: The group wants to raise $1,200.

Step-by-step explanation:

We can use a proportion to solve.

part/whole = percent/100

If we insert the values:

276/x = 23/100

We can cross multiply.

276 x 100 = 27,600

27,600 / 23 = 1,200

$1,200 is the answer.

aalyn [17]

Answer: The answer should be 38.

I also saw that you placed a t after the -2 so I wasn't sure if it was a mistake or if it was on purpose or you left another t out of the problem on accident.

Step-by-step explanation:

2.3   (14+6)   -2 to the power of three

2.3    (20)     -2 to the power of three

2.3     (20)     -8

    46-8

      38

I really hoped this helped and if I got it wrong with the t just reply to me c:
