Find the missing length for a right triangle with hypotenuse of 18 and a leg length of 6. Round to the nearest whole number if n

DiKsa [7]

$a^2 + b^2 = c^2$

$a^2 + 6^2 = 18^2$

$a^2 + 36 = 324$

$a^2 = 288$

$a = \sqrt{288}$

$a = \sqrt{144 \times 2}$

$a = 12\sqrt{2}$

$a \approx 17$

Find the perimeter of the rectangle with the following vertices. (−6, −2), (0, −10), (5, 2), (−1, 10) 23 52 46 40

Licemer1 [7]

Answer:

Step-by-step explanation:

See attached for reference

The points given:

(−6, −2), (0, −10), (5, 2), (−1, 10)

They form a rectangle as seen in the picture.

We can notice that this is a parallelogram, as respective lines have same difference of coordinates.

So calculating only the two of the sides will be sufficient to get its perimeter:

a = √(-1+6)² + (10+2)² = √25+144 = √169= 13
b = √(0+6)² + (-10+2)² = √36+64 = √100 = 10

So, the perimeter:

P = 2(13+10) = 46
