Answer:

For the first one:

D) The perpendicular bisector of line MN

For the second one:

You need a protractor (angle ruler) to measure the angle. After finding the measurement, divide it into two. After finding the result, find the point that has that angle.

Example -

The pie measures 120°.

120° ÷ 2 = 60°

Find the point that measures 60° and connect the points (from the start to the edge of the pie).

For the third one:

C) m∠ABD ≅ m∠CBD

Is the point P (2,8) on the inside or outside of the circle described with equation x^2+y^2=100?

kykrilka [37]

Points $(x,y)$ on the circle satisfy $x^2+y^2=100$ .

Points inside the circle satisfy $x^2+y^2$ .

Points outside the circle satisfy $x^2+y^2>100$ .

We have

$2^2+8^2=4+64=68$

so the point (2, 8) lies inside the circle.

Find the area please

tatuchka [14]

Answer:

Step-by-step explanation:

Recall that the area of a triangle is given by:

$\displaystyle A = \frac{1}{2} bh$

In this case, the base is x and the height is y. Hence:

$\displaystyle A = \frac{1}{2} xy$

We can write the following ratios:

$\displaystyle \sin \alpha = \frac{x}{12} \text{ and } \cos \alpha = \frac{y}{12}$

Solve for x and y:

$\displaystyle x = 12\sin \alpha \text{ and } y = 12\cos \alpha$

Substitute:

$\displaystyle A = \frac{1}{2}\left(12\sin \alpha\right)\left(12\cos \alpha\right)$

And simplify. Hence:

$\displaystyle A = 72\sin \alpha \cos\alpha$

In conclusion, our answer is D.
