Step-by-step explanation:
Answer:
a)
The point that is equidistant to all sides of a triangle is called the <u>incenter</u>.
The incenter is located at the intersection of bisectors of the interior angles of a triangle.
b)
The point that is equidistant to all vertices of a triangle is called the <u>circumcenter</u>.
The circumcenter is located at the intersection of perpendicular bisectors of the sides of a triangle.
c)
<em>See the attachment</em>
The blue lines and their intersection shows the incenter.
The red lines and their intersection shows the circumcenter.
As we see the red point- the <u>circumcenter </u>is closer to vertex B.
Answer:
2b +2 or (b+b)+2
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
To answer this question, you must isolate the variable y.
Step 1.
add 2 to each side to isolate 2y
2y-2+2=16+2
the twos on the left cancel out and you are left with: 2y=18
Step 2.
divide each side by 2 to isolate y completely
2y/2=18/2
y=9
Using the law of sines, supposing C = 30º, the angle of each observer with the sailboat is:
<h3>What is the law of sines?</h3>
Suppose we have a triangle in which:
- The length of the side opposite to angle A has length a.
- The length of the side opposite to angle B has length b.
- The length of the side opposite to angle C has length c.
The lengths and the sine of the angles are related according to the following rule:
![\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csin%7BA%7D%7D%7Ba%7D%20%3D%20%5Cfrac%7B%5Csin%7BB%7D%7D%7Bb%7D%20%3D%20%5Cfrac%7B%5Csin%7BC%7D%7D%7Bc%7D)
The measure of angle B is found as follows:
sin(B)/10 = sin(C)/20
sin(B)/10 = 0.5/20 (sin(C) = 0.5)
sin(B) = 5/20
sin(B) = 0.25
B = arcsin(0.25)
B = 14º.
The measure of angle A is found as follows:
sin(A)/25 = sin(C)/20
sin(A)/25 = 0.5/20 (sin(C) = 0.5)
sin(A) = 12.5/20
sin(A) = 0.625
A = arcsin(0.625)
A = 136º.
<h3>Missing information</h3>
The problem is incomplete, hence we suppose that the angle C is of 30º and problem asks for the angle measure of each angle.
