2+8-z=-24 (add the numbers)
10-z=-24 (move the constant to the right)
-z=-24-10 (calculate)
-z=-34 (change the signs)
Z=34

Put 34 in place of the z. The problem is basically asking what equation can you do to get -24?

2 + 8 - 34 = -24

Answer:

10.71 yd

Step-by-step explanation:

First let's find the radius of the quarter circle.

area =\frac{1}{4} \pi {r}^{2} \\  7.065 = \frac{1}{4} *3.14 {r}^{2}  \\  \frac{7.065}{3.14}  = \frac{1}{4} * \frac{3.14 {r}^{2} }{3.14}  \\  9 =  {r}^{2}  \\  \sqrt{9}  = r \\ 3 yd= r

Now let's find the arc length of this quarter circle.

\frac{90}{360}  \times 2\pi \: r \\  \frac{1}{4}  \times 2 \times 3.14 \times 3 \\  =  \frac{9.42}{4}  \\  = 4.71yd \\

Now let's find the perimeterperimeter \\  = arc \:  \: length + radius + radius \\  = 4.71 + 3 + 3 \\  = 10.71yd

tan-32/24

Step-by-step explanation:

SOHCAHTOA

sin is opposite over the hypotenuse

cosine is adjacent over hypotenuse

tan is opposite over adjacent

plug in the numbers corresponding with angle B and you get your formulas

so sorry if my explanation was bad
