Can y’all help me? i’ll literally fail if i don’t get these right lol

Answer:

63 degrees.

Step-by-step explanation:

TRaingle ABC is isosceles so the base angles are equal That is < BAC = < BCA.

<BAC = 180 - 117 = 63 degrees ( because it is adjacent to <x which is 63 degrees).

So < BCA = <BAC = 63 degrees.

Finally y = 63 degrees ( vertical angles are equal).

Find the area and the circumference of a circle with radius 3 m. Use the value 3.14 for π, and do not round your answers. Be sur

Gennadij [26K]

Circumference: 18.84 m

Area: 28.26 $m^{2}$

Explanation

For circumference, use the formula $\pi$ *d, where d=the diameter(the radius times 2).

For area, use the formula $\pi$ $r^{2}$ , where r=the radius. Make sure to square the radius first before multiplying by pi!

A good way to remember these formulas is Cherry(circumference) Pi( $\pi$ ) is Delicious(diameter) and Apple(area) $\pi$ $r^{2}$ ("are too")

3. Rectangle ABCD is shown on the coordinate grid below.

VMariaS [17]

Answer:

A. 8 units

Step-by-step explanation:

Coordinates of A = (-2, -2)

Coordinates of C = (5, 2)

Use distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ to calculate the length of diagonal $\overline{AC}$ .

Let,

$A(-2, -2) = (x_1, y_1)$

$C(5, 2) = (x_2, y_2)$

$d = \sqrt{(5 -(-2))^2 + (2 -(-2))^2}$

$d = \sqrt{(7)^2 + (4)^2}$

$d = \sqrt{49 + 16} = \sqrt{65}$

$d = 8.1$ (nearest tenth)

Therefore, the closest to the length of diagonal $\overline{AC} = 8 units$

I dont know how to do this pls help

Alecsey [184]

Answer:

1) 225

2) 2304

Step-by-step explanation:

Use geometric mean of legs

$x = \sqrt{(16+9)^2 * 9^2} = \sqrt{25^2 * 9^2} = 25 * 9 = 225$

Use geometric mean of altitude

$x = \sqrt{(100-36)^2 * 36^2} = \sqrt{64^2 * 36^2} = 64 * 36 = 2304$
