Answer:

  x = 78°

Step-by-step explanation:

The sum of the interior angles of a triangle is 180°.

  x + a + b = 180°

  x = 180° -a -b . . . . . . . . add -a-b to both sides

  x = 180° -54° -48°

  x = 78°

Jim is enclosing a rectangular garden with 170 feet of fencing. The length of the garden is 10 feet more than twice it’s width,
Darina [25.2K]

Answer:

1,500\ ft^2

Step-by-step explanation:

Let

L ----> the length of the rectangular garden in feet

w ---> the width of  the rectangular garden in feet

step 1

Find the width

we know that

The perimeter of the rectangular garden is

P=2(L+W)

P=170\ ft

so

170=2(L+W)

Simplify

85=(L+W) ----> equation A

L=2W+10 ----> equation B

substitute equation B in equation A and solve for W

85=(2W+10+W)

85-10=3W

3W=75

W=25\ ft

Find the value of L

L=2(25)+10=60\ ft

step 2

Find the area

we know that

The area of the rectangular garden is

A=(LW)

substitute the values

A=(60)(25)=1,500\ ft^2

___,36 ,108 ,324 ,972
hjlf
12

First figure out of it is a arithmetic or geometric sequence, in this case it is a geometric sequence because you have to multiply, not add to find the next number.

Divide one number, I'll pick 324 by the number before it, 108, you get three.

Now divide 36 by 3, you get 12.

To check, multiply 12 by 3, you get 36, multiply that by 3, you get 108, and so on and so forth.
