Opposite angle of a quadrilateral add up to 180 degrees.

This means Angle A plus Angle C equal 180.

We can solve for X using that, then solve for Angle B.

2x-7 + x +4 = 180

Simplify:

3x -3 = 180

Add 3 to each side:

3x = 183

Divide both sides by 3:

x = 183 /3

x = 61

Now we know x, replace x with 61 in the equation for Angle B:

Angle B = 2x+3 = 2(61) +3 = 122 +3 = 125 degrees.

I encourage everyone taking this test to take my word that it's 125.

What is theoretical vs practical domain in an exponential equation. Plz provide an example too
olya-2409 [2.1K]

Answer:

The theoretical probability of an event occurring is an "expected" probability based upon knowledge of the situation. It is the number of favorable outcomes to the number of possible outcomes. Example: ... There are 6 possible outcomes when rolling a die: 1, 2, 3, 4, 5, and 6. The only favorable outcome is rolling a 6.Practical domains and ranges narrow the solution sets to be realistic within defined parameters.The possible values of "x" is called the domain. The possible values of "y" is called the range.

the zeros of a parabola are -4 and 2, and (6, 10) is a point on the graph. which equation can be solved to determine the value o
natka813 [3]
Sure this question comes with a set of answer choices.

Anyhow, I can help you by determining one equation that can be solved to determine the value of a in the equation.

Since, the two zeros are - 4 and 2, you know that the equation can be factored as the product of (x + 4) and ( x - 2) times a constant.  This is, the equation has the form:

y = a(x + 4)(x - 2)

Now, since the point (6,10) belongs to the parabola, you can replace those coordintates to get:

10 = a (6 + 4) (6 - 2)

Therefore, any of these equivalent equations can be solved to determine the value of a:

10 = a 6 + 40) (6 -2)

10 = a (10)(4)

10 = 40a
