Circumcenter is where three perpendicular bisectors intersect and incenter is where the three angle bisectors intersect.

Way to find them and the theorems are mentioned below.

Step-by-step explanation:

To find Incenter :

Construct angle bisectors of each angle of the triangle and their intersection  point gives the incenter.

To find Circumcenter:

Construct perpendicular bisectors of all sides of triangle and their intersection point gives the circumcenter.

Circumcenter Theorem: It states that the vertices of a triangle are equidistant from the circumcenter.

Incenter Theorem: It states that the incenter is equidistant from the sides of the triangle.

What is the slope? Loooook atttt the chartttt ✨
gavmur [86]

Answer:

m = 3/5

Step-by-step explanation:

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step 1: Find 2 coordinates

(0, 80)

(-50, 50)

Step 2: Find slope <em>m</em>

m = (50 - 80)/(-50 - 0)

m = -30/-50

m = 3/5

Are these lines parallel or not: L1: (1,2), (3,1), and L2: (0,-1), (2,0)
Phoenix [80]

First find the slope of the first line

L1

m = ( y2-y1)/(x2-x1)

m = ( 1-2)/(3-1)

= -1/2

Now find the slope of the second line

L2

m= ( y2-y1)/(x2-x1)

= ( 0 - -1)/(2 -0)

= (0+1)/(2-0)

= 1/2

Parallel lines have the same slope

These lines do not have the same slope, they are different by a negative sign.

These lines are not parallel.

Workers are grouped by their areas of expertise and are placed on at least one team. 20 are on the marketing team, 30 are on the
liubo4ka [24]

Answer: C. 74

Step-by-step explanation:

Let M= Number of workers are in marketing team .

S = Number of workers are in Sales team.

V = Number of workers are in Vision team.

As per given , we have

n(M) = 20 , n(S) = 30 , n(V) = 40

n(M∩S) = 5  ,  n(V∩S) = 6  ,  n(M∩V)  = 9

n(M∩S∩V) =4

Using formula of sets , we get

n(M∪S∪V) =n(M)+n(S) +n(V) -n(M∩S) - n(V∩S)-n(M∩V) +n(M∩S∩V)

Substitute the corresponding values , we get

n(M∪S∪V) =20+30+40-5-6-9 +4

=  74

∴ The number of workers are in at least one team = 74

Therefore , the total number of workers =74

Hence, the correct option is : C. 74

Answer:

143 calories

Step-by-step explanation:

We can use a ratio to solve

110 calories      x calories

----------------- = ---------------

28.4 grams         36.92 grams

Using cross products

110* 36.92 = 28.4 * x

Divide each side by 28.4

110*36.92 / 28.4 = x

143 calories = x
