Answer:

perimeter = 40

area = 46(unit)^2

Step-by-step explanation:

Perimeter - all sides added together

Find unknown sides (8-3 = 5, 12-2 = 10)
Add all sides together (8+2+5+10+3+12 = 40)

Area - Length multiplied by width

Divide shape into two rectangles (#1 is 2x5 and #2 is 3x12)
Find individual area (rectangle #1: 2*5 = 10 / rectangle #2: 3*12 = 36)
Add areas together (10+36 = 46)
Finish with unit squared (46___^2)

Determine whether line segment FG is tangent to circle E. True or False

lisabon 2012 [21]

The tangent line to a circle makes an angle of 90 degrees with the radius.
If |FG| is tangent to circle E. then
30^2 = 26^2 + 17^2
which is not true.
Therefore, line segment FG is not tangent to circle E.

Answer:

I would say it's -0.8

Step-by-step explanation:

Since 3 is pretty far, I'm assuming -2 is at the left end of the line, so -.8 seems like the most reasonable answer.

How do you find the legs of a right triangle when only given the hypotenuse?

tangare [24]

Answer:

We know that a^2+b^2=c^2. The 45° angle lets us know that y=x (45+45+90=180), so the problem is y^2+x^2=4sqrt of 2

$4 \sqrt{2} = \sqrt{32 } \\ \sqrt{32} ^{2} = 32$

So you get y^2+x^2=32, and from there, since we know x and y are equal, you can just divide 32 by 2 then take the square root of that, so the answer should be 4 for both x and y

Step-by-step explanation:

let me know if I'm wrong lol

Answer:

Disagree

Step-by-step explanation:

Remember rotating 90 degrees means (y,-x)

A= (1,2)

A'= (2,-1)

So it is disagreed.

Hope this help :)
