INSCRIBED ANGLES PLZ HELP ASAP

Taya2010 [7]

The answer is 46°.

The measure of an inscribed angle is equal to (1/2) the measure of the intercepted arc.

That means that, since ADC is 23 degrees, doubling that gives you 46 degrees, the measure of the intercepted arc.

Central angles are equal to the measure of the intercepted arc, which in this case is the same arc we just calculated.

Therefore it's 46.

A rectangular plot measures 20 ft. By 30ft. A 3ft wide side walk surrounds it. Find the area of the side walk

r-ruslan [8.4K]

Answer:

336 feet²

Step-by-step explanation:

If we have a rectangle that is 30 by 20 feet, that means the area of that rectangle would be 20 × 30 feet squared, which is 600 ft².

If there is a 3 feet sidewalk surrounding it, that means that the end of the sidewalk will extend 3 feet extra around each side of plot. Since there are two ends to one side, that means an extra six feet is added on to each dimension. Therefore, 36 × 26 are the dimensions of the sidewalk+plot. 36 × 26 = 936 ft².

To find the area of the sidewalk itself, we subtract 600 ft² from 936 ft². This gets us with 336 ft².

Hope this helped!

What is the value of x?<br><br> Enter your answer in the box.<br><br> x =

Dmitry_Shevchenko [17]

Answer: x = 20

We know opposite angles are equivalent so we can set both of these expressions equal to each other to solve for x.

3x + 50 = 6x - 10
50 = 3x - 10 (subtract 3x from both sides)
60 = 3x (add 10 to both sides)
20 = x (divide both sides by 3)
