I would appreciate it if someone could help answer this problem:)

Mathematics

Vesna [10]2 years ago

Answer:

x = 85°

Step-by-step explanation:

As noticed this is a Pentagon (5 sided polygon); therefore to find x, first we have to find the sum of it's interior angles;

Sum of interior angles of a pentagon = (n - 2) * 180°

=> Sum of interior angles of a pentagon = (5 - 2) * 180°

=> Sum of interior angles of a pentagon = 3 * 180

=> Sum of interior angles of a pentagon = 540

Now that we know the sum of interior angles, we can set up the equation and solve for x;

115 + 95 + 115 + 130 + x = 540

455 + x = 540

x = 540 - 455

x = 85

Hope this helps!

The answer would be A. m= -3/5 and b=-4/5
"m= -5-1 divided by 7--3
or, -6/10
or, -3/5.

to find the (B)

<span><span>(-3,1). y=mx+b or 1=-3/5 × -3+b, or solving for b: b=1-(-3/5)(-3). b=-4/5.</span><span>(7,-5). y=mx+b or -5=-3/5 × 7+b, or solving for b: b=-5-(-3/5)(7). b=-4/5.</span></span>See! In both cases we got the same value for b. And this completes our problem.

When you are determining the probability of an event, why must the probability be between 0 and 1? Explain your answer.
Airida [17]

Answer:

The probability of an event will not be less than 0. This is because 0 is impossible (sure that something will not happen). The probability of an event will not be more than 1. This is because 1 is certain that something will happen.

What is an equation of the line that passes through the points (2, -6)(2,−6) and (-1, 6)(−1,6)?
Crank

Answer:

y = -4x + 2

Step-by-step explanation:

To figure out the slope, plug the coordinates in the formula.

y2 - y1 / x2 - x1

= 6 - (-6) / -1 -2

= -4

Now you need to find the y-intercept, take the coordinates and plug them into your equation so far, which is y = -4x + b

y = -4x + b

-6 = -4(2) +b

-6 = -8 + b

2 = b
