Answer – TrueA design is said to have Rotational symmetry if all its characteristics remain the same after it has been rotated about an axis lying in its plane. In other words, rotational symmetry is the quality possessed by a shape has when it looks the same after it has undergone some rotation by a partial turn about an axis lying in its plane. Rotational symmetry is also referred to as radial symmetry.
To evaluate this expression, you will perform all the multiplication first then add those answers.
268x12 + 268x 23 + 732x35
3216 + 6164 + 25620
9380 + 25620
35000
The answer is 35,000.
- Given - <u>a </u><u>circle </u><u>along </u><u>with </u><u>the </u><u>measure </u><u>of </u><u>two </u><u>angles </u><u>at </u><u>the </u><u>centre</u>
- To calculate - <u>measure </u><u>of </u><u>angle </u><u>JGH</u>
We know that ,
<u>the </u><u>sum </u><u>of </u><u>all </u><u>the </u><u>angles </u><u>at </u><u>the </u><u>centre </u><u>or </u><u>the </u><u>sum </u><u>of </u><u>all </u><u>the </u><u>central </u><u>angles </u><u>of </u><u>a </u><u>circle </u><u>equals </u><u>3</u><u>6</u><u>0</u><u>°</u>
therefore , <u>option </u><u>(</u><u> </u><u>c </u><u>)</u><u> </u><u>8</u><u>6</u><u>°</u> is correct

Remember that perimeter is the sum of the lengths of the sides. The way to find the length of the sides is
where
is one endpoint of one line, while
is the other endpoint of the same line. Repeat this formula for each side and add them all together to get your perimeter
