2/4 is equal to a half

a circle is 360° and half of 360 is 180

so your answer is B. 180°

hope this helped

B:180 degrees because a circle is 360 degrees and half of 360 is 180. I'm learning this too lol

The distance between the points (1,2) and (x,-1) is 5 units. Find the possible values of x

Mariulka [41]

Answer:

-3,5

Step-by-step explanation:

$d = \sqrt{(x _{2} - x _1) {}^{2} + (y _{2} - y _{1} {} ) {}^{2} }$

$5 = \sqrt{(x - 1) {}^{2} + ( - 1 - 2) {}^{2} }$

$5 = \sqrt{(x - 1) {}^{2} + ( - 3) {}^{2} }$

$25 = (x - 1) {}^{2} + 9$

$16 = (x - 1) {}^{2}$

$4 = x - 1$

$x = 5$

$- 4 = x - 1$

$x = - 3$

∠5 is a supplement of ∠6, and m∠5=78°. Find m∠6.

Answer:

$102^\circ$

Step-by-step explanation:

Given that:

$\angle 5$ is a supplement of $\angle 6$ .

m $\angle 5$ = 78°

To find:

m $\angle 6$ = ?

Solution:

First of all, let us learn about the concept of an angle being a supplement of the other angle.

$\angle B$ is known as supplement of $\angle A$ , if sum of the two angles is equal to 180°.

$i.e. \angle A +\angle B=180^\circ$ .

For example, angle made on one side by a line intersecting the other line are supplement of each other.

Here, we are given that $\angle 5$ is a supplement of $\angle 6$ .

In other words:

$\angle 5+\angle 6=180^\circ$

Putting value of $\angle 5$ :

$\Rightarrow 78^\circ+\angle 6=180^\circ\\\Rightarrow \angle 6 =180^\circ-78^\circ\\\Rightarrow \bold{\angle 6 =102^\circ\\}$

So, the answer is: $102^\circ$
