Plz answer last question and im lost!
harkovskaia [24]

Answer:

\pi radian

Step-by-step explanation:

We know that angle for a full circle is 2\pi

In the given figure shape is semicircle

hence,

angle for semicircle will be half of angle of full circle

thus, angle for given figure = half of  angle for a full circle = 1/2 * 2\pi = \pi

Thus, answer is \pi radian

alternatively, we also know that angle for a straight line is 180 degrees

and 180 degrees is same as \pi radian.

For what values of x is the following equation satisfied : 3x+9 = 21+7x ?
olya-2409 [2.1K]
First of all, the first power of 'x' is the highest power in the whole equation,
so we only expect one solution.

You said that <span><u>3x+9 = 21+7x </u>

Subtract 3x from each side:

9 = 21 + 4x

Subtract 21 from each side:

-12 = 4x

Divide each side by 4 :

<u>-3 = x </u>
