Step-by-step explanation:

Let x be the size of 1 of the 2 congruent angles.

The size of the other congruent angle is also x.

Since sum of angles in a triangle = 180°,

Measure of 3rd angle in the triangle

= 180° - 1st angle - 2nd angle

= (180 - 2x)°.

Answer:

The Isosceles Triangle Theorem, All interior angles of a triangle add up to 180 degrees. Basically the equation would be (angle 1) + (angle 2) + (angle 3) = 180. whichever angle you dont have you replace with x and solve for it. For example if you had a triangle with two congruent angles of 36 then it would be 36+36+x=180 and you would solve it like any other equation eventually showing you that x = 108. it also works backwards if you are trying to solve for the 2 missing congruent angles.

-30 < x/-4 must be simplified

Norma-Jean [14]

Answer:

120 > x

Step-by-step explanation:

multiply -4 on both sides, -30 * -4 = 120

since you multiplied by a negative you change the sign

A random sample of n = 4 scores is obtained from a normal population with m = 30 and s = 8. what is the probability that the sam

tangare [24]

the probability that the sample mean will be smaller than m = 22 is 0.02275.

For the given question,

A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.

Here sample size, n = 4

mean, μ = 30

standard deviation, σ = 8

The probability that the sample mean will be smaller than m = 22 is

z = $\frac{m-\mu}{\frac{\sigma}{\sqrt{n} } }$
