The answer is c.
The distance from the centre of the circle to any point on the circumference of the circle is called the radius.
Question 1:
By definition, the area of a regular hexagon, depending on its sides, is given by:
Where,
L: side of the regular hexagon.
Substituting values we have:
Rounding to the nearest hundredth we have:
<span><span>
Answer:
</span>
The area of a regular hexagon with a side length of 12 cm is:
</span>
Question 2:
By definition, sides of a triangle 30-60-90 are given by:
Largest side:
Smallest side: x
hypotenuse: 2x
Therefore, since the smallest side length measures 5 cm, then the hypotenuse is:
Answer:
the length of the hypotenuse when the shorter leg is 5 cm is:
10 cm
Question 3:
The first thing you should know for this case, is that angle 30, is a notable angle.
Therefore, the values of the sine are defined for notables angles.
The notable angles are:
0, 30, 45, 60, 90
Therefore, the value of sine (30) is given by:
sine (30) = 1/2
Answer:
the exact value of sin 30 ° is:
sine (30) = 1/2
Because x is greater than, or equal to one, your graph would be a solid vertical line, along the 1 value. The right side of this line would be shaded, because your inequality includes everything to the right of this line.
A quadrilateral's angles always add up to 360 degrees. So you add the angles you have 24+100+78=202 and then subtract that from 360 which will give you 158
