For ΔABC, the measure in degrees of angles A, B, and C are 30, 4x, and 50 respectively. What is the value of x?

Luba_88 [7]

Answer:

x=25

Step-by-step explanation:

The area of a traingle is 180 degrees, so we subtract 30 and 50 from 180. we are then left with 100 degrees, divide by 4 and we get that x=25.

What is the area of this figure?

scoundrel [369]

The answer would be 189 cm². Multiply the legs of the triangle (12 x 9), and keep that answer. Usually, to measure the area of a triangle, you would multiply the legs and divide by 2, but since there are two congruent triangles in the same shape here, you don't have to. Next step would be to add the area of the square in the middle (9 x 9). Add 12x9 to 9x9 (108 + 81) to get 189.

Hope this helps! If it did, would my mind marking my answer as Brainliest? Thanks :D

Answer:

The standard deviation of the sum is of 8.06.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Sum of normal variables:

When we add two normal variables, the mean is the sum of their means, and the standard deviation is the square root of the sum of their variances. In this question:

First intersection -> Standard deviation of 4

Second intersection -> Standard deviation of 7

Sum:

$\sigma = \sqrt{4^2 + 7^2} = \sqrt{65} = 8.06$

The standard deviation of the sum is of 8.06.
