Answer:

56°, 84°, 40°

Step-by-step explanation:

The three angles of triangles have measures of 56°, (2x + 4)º, and xº.

We need to find the measures of the three angles of the triangle.

We know that, the sum of angles of triangle is equal to 180º. Using this property we get :

56°+ (2x + 4)º + xº =180º

Solving for x.

60 + 3x = 180

3x = 120

x = 40º

Other angle, = 2x+4

= 2(40)+4

= 80+4

= 84º

So, the measures of the three angles of the triangle are 56°, 84°, 40°. Hence, the correct option is (c).

suppose the theoretical probability of winning a prize in the carnival game 0.18 based on this probability how many more custome

Harlamova29_29 [7]

The number of customers I would have expected to win the prize is 6.

<h3>How many more customers would I have expected to win the prize?</h3>

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

Based on the probability, the number of customers I would have expected to win: 0.18 x 300 = 36

How many more people I would have expected to win : 36 - 30 = 6

Need a math person's help ASAP.

Crank

we know that

the equation of the line in the point-slope form is equal to

$y-y1=m(x-x1)$

we have

$y+6=45(x+3)$

the point is $(-3,-6)$

the slope is $m=45$

<u>With the slope and the point, find the second point</u>

$m=45=\frac{4.5}{0.10}$

the x-coordinate of the second point will be

$-3+0.10=-2.90$

the y-coordinate of the second point will be

$-6+4.5=-1.5$

the second point is $(-2.90,-1.5)$

Graph the line

Amanda [17]

Answer:

(x,y) = (x, -2x²+6x+8), X∈R

Step-by-step explanation:

y= -2x²+6x+8

y=-2(x-4)×(x+1)

-2x²+6x+8= -2(x-4)×(x+1)

x∈R

(x,y) = (x, -2x²+6x+8), x∈R
