Which equation can you use to solve for x? x + 56 = 180 x + 146 = 180 180−x=146 x + 56 = 146 The figure contains a pair intersec
ting lines. One of the four angles formed by the intersecting lines is labeled 146 degrees. The angle opposite and not adjacent to this angle is broken into two smaller angles by a ray that extends from the point where the two lines intersect. One of these smaller angles is labeled 58 degrees, and the other smaller angle is labeled x degrees.

we know that
angle 146</span>° and angle (56°+x°) area equal -----> by vertical angles
so
146=56+x
therefore
the answer is

Answer:
The critical value that corresponds to a confidence level of 99% is, 2.58.
Step-by-step explanation:
Consider a random variable <em>X</em> that follows a Binomial distribution with parameters, sample size <em>n </em>and probability of success <em>p</em>.
It is provided that the distribution of proportion of random variable <em>X, </em>, can be approximated by the Normal distribution.
The mean of the distribution of proportion is,
The standard deviation of the distribution of proportion is, .
Then the confidence interval for the population proportion <em>p</em> is:
The confidence level is 99%.
The significance level is:
Compute the critical value as follows:
That is:
Use the <em>z</em>-table for the <em>z-</em>value.
For <em>z</em> = 2.58 the P (Z < z) = 0.995.
And for <em>z</em> = -2.58 the P (Z > z) = 0.005.
Thus, the critical value is, 2.58.
