Can someone please help me find the measure of the exterior angle.
dimulka [17.4K]

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  because they are supplementary angles

k = 140°

nata0808 [166]

9514 1404 393

Answer:

  $13,916.24

Step-by-step explanation:

First, we need to find the value of the CD at maturity.

  A = P(1 +rt) . . . . simple interest rate r for t years

  A = $2500(1 +0.085·3) = $2500×1.255 = $3137.50

__

Now, we can find the value of the account with compound interest.

  A = P(1 +r)^t . . . . . rate r compounded annually for t years

  A = $3137.50 × 1.18^9 = $13,916.24

The mutual fund was worth $13,916.24 after 9 years.

The length of a rectangle is 4 more than twice the width. The perimeter is 74 feet. Find the length and width of the rectangle.
mafiozo [28]
(2*length)+(2*width)=perimeter
length=4+2w
(2(4+2w))+(2(w))=74
74=(8+4w)+(2w)
74=6w+8
66=6w
w=11
length=4+2(11)
l=4+22
l=26
