How do you prove that vertical angles are congruent?

2 answers:

If they're the same, then they are congruent. If they're on an image, you can use angles in parallel lines, such as Z (alternate) angles, F (corresponding) angles, or vertically opposite angles to show that they are equal. I hope this helps! Let me know if you need further explanation :)

When two lines intersect to make an x, angles on opposite sides of the X are called vertical angle. and both angles are equal, give me a second and i will give you an example.

Step-by-step explanation:

Given parameters:

Weight of the small box = 125pounds

Unknown:

Weight of the larger box = ?

Solution:

The large box weighs $3\frac{1}{3}$ times as the small box:

So;

= 125pounds x $\frac{10}{3}$

= 416.7pounds

Adult men have heights with a mean of 69. 0 inches and a standard deviation of 2. 8 inches. find the z-score of a man who is 71.

Anarel [89]

The value of the z score is 1.03.

According to the statement

we have given that the value of mean and standard deviation and we have to find the value of the z score.

So, For this purpose we know that the

Z-score indicates how much a given value differs from the standard deviation. The Z-score, or standard score, is the number of standard deviations a given data point lies above or below mean.

And the given values are:

mean value = 69 inches

s.d value = 2.8 inches

And the value of x is 71.9 inches.

So, The Z score is

z = x - mean / standard deviation

substitute the values in it then

z = 71.9 - 69 / 2.8

then

z = 2.9 /2.8

z = 1.03

So, The value of the z score is 1.03.
