Help with finding the area and perimeter

torisob [31]

Using the Pythagorean theorem, 12^2 + 12^2 = 288 (equal lengths of a right-angle triangle). the square root of 288 is 16.9 (could be rounded to 17).

Rounding up to 17, the perimeter (P) would be 41. Without rounding, it would be 40.9.

Using the 17 measurement as the Base, the height would come out to 4.82. This can be used to find the Area, which comes out to being 41.

If you would like to double check, the measurements based on the picture are:
Sides: 12, 12, 17
Angles: 45, 45, 90

I hope this helps!

Solve for m. (-11/6) + m = -2/9

3241004551 [841]

Answer:

m = $\frac{29}{18}$

Step-by-step explanation:

=> (-11/6) + m = -2/9

Adding 11/6 to both sides

=> m = $-\frac{2}{9} + \frac{11}{6}$

LCM = 18

=> m = $\frac{-4+33}{18}$

=> m = $\frac{29}{18}$

Can someone answer the second question?

bezimeni [28]

Answer:

comparing powers of equal bases

x^2+4x+4 = 9x +18

x^2 -5x -14=0

x^2 -7x +2x -14=0

x^2 -7x +2x - 14=0

(x-7) x + 2(x-7) =0

(x-7) (x+2) =0

x= - 2 , 7

The volume of a sphere is 5000 pi m 3 what is the surface area

Nikitich [7]

$V = \frac{4}{3}\pi r^3
\\ 5000\pi = \frac{4}{3} \pi r^3
\\ 5000 = \frac{4}{3} r^3
\\ \frac{3}{4} * 5000 = r^3
\\ 3750 = r^3
\\ r = 15.536
\\ SA = 4 \pi r^2
\\ SA = 4\pi (15.536)^2
\\ SA = 3033.11$

The hypotenuse in this 45-45-90 triangle is given. How would you find the length of a leg

Viefleur [7K]

Answer:

The length of the legs of the triangle is 8 units.

Step-by-step explanation:

45-45-90 triangle

A 45-45-90 triangle is a special case of a right triangle in which both legs l have the same value and the hypothenuse is h. By the Pythagorean Theorem:

$2l^2 = h^2$
