Answer:

The angles are vertical, and the value of x is 128 degrees

Step-by-step explanation:

You can tell vertical angles apart from adjacent by looking at their position. Adjacent angles are side by side, right next to each other. Vertical angles are directly across from each other, with their points touching.

Since the angle measures of vertical angles are equal, the value of x is 128

i hope this helps

6 + −28 − x = -2<br> -------------<br> x
nexus9112 [7]
The answer is x=-20.
6+ -28 -x =-2
You first add 28 to each side=6+-x=26 then you minus 6 from each side=-x=20.
Then you divide 20 by -x resulting in x=-20

Answer:

V= 42.41

Step-by-step explanation:

V = \pi r^{2}\frac{h}{3}

where r is the radius = 3 and h is the height = 4.5

V= \pi × 3^{2} × \frac{4.5}{3}

V = 42.41

The simple interest on a sum of money invested for 6 months at 5% per annum is $1680. Find the amount of money invested
olga55 [171]

9514 1404 393

Answer:

  $67,200

Step-by-step explanation:

The amount if interest is given by the formula ...

 I = Prt

where P is the amount invested, r is the annual rate, and t is the number of years. Here, we want to find P when r = 0.05 and t = 1/2 such that I = 1680.

  P = I/(rt) = $1680/(0.05·0.5) = $1680/0.025

  P = $67,200

The amount invested was $67,200.
