Answer:

x = 75°

Step-by-step explanation:

There are many Circle Geometry Rules. We will be using the following:

<u>The angle at the centre of the circle is twice the angle at the circumference.</u>

x = the angle opposite 285 - x.

This means that 360 - (285 - x) = 2x

360 - 285 + x = 2x

75 + x = 2x

We can simplify this by taking away x from both sides.

75 = x

We can check this by substituting x into the orginal equation.

360 - (285 - x) = 2x

360 - (285 - 75) = 2 * 75

360 - 210 = 2 * 75

150 = 2*75

150 = 150

lord [1]

Answer:

50 + 1 + $\frac{2}{10}$ + $\frac{4}{100}$ + $\frac{2}{1,000}$

Step-by-step explanation:

This is the answer because:

1) 50 and 1 equal to 51

2) The fraction forms of a decimal number is: the decimal number/the decimal number place value

3) Therefore, the answer is 50 + 1 + $\frac{2}{10}$ + $\frac{4}{100}$ + $\frac{2}{1,000}$
