x=96


all interior angles equal 180


Subtract exterior andgles by 180 to get interior angles because they are supplementary

180-134=46

180-130=50


Get the third angle inside the triangle

180-50-46=84


subtract by 180 to get x because they are supplementary

180-84=96


Therefore x =96

F(x)=(x+4) 2 −25<br><br> smaller x =<br><br> larger x = <br><br> NEED THIS ASAP
miss Akunina [59]

f(x)=(x+4) ^2 −25

to solve set equal to zero

0 =(x+4) ^2 −25

add 25 to each side

25 = (x+4) ^2

take the square root of each side

square root (25) =(x+4)

+- 5 = (x+4)

5 = x+4      -5 = x+4

subtract 4 from each side

1 =x            -9 =x

Sirgeo wants to fence in a circular portion of his backyard for a place space for his dog. Determine the area of the largest por
pickupchik [31]

Answer:

  412.7 square feet

Step-by-step explanation:

A circle of circumference 72 ft will have a radius given by ...

  C = 2πr

  (72 ft) = 2(3.14)r

  r = (72 ft)/(6.28) ≈ 11.465 ft

The area of a circle with that radius is ...

  A = πr² = 3.14(11.465 ft)² ≈ 412.7 ft²

Sirgeo can enclose a circular area of about 412.7 square feet with 72 feet of fence.
