How do I do this I’ll mark u brainliest pls ?
nataly862011 [7]

Answer:

1. is a 30 60 90 triangle so x = 30

pardon my bad handwriting for below

2.

STEP 1: subtract the angle you have from 180

STEP 2: add your x values together, if there is a non x number (such as + 10) balance it out on the other side by adding or subtracting

STEP 3: divide so that x has no coeffecient in front of it

STEP 4: substitute x values with the value you got

STEP 5: verify by adding the angles you got, it'll be correct if it equals 180

Find the means of these numbers 3,7,2,9,4,7,3,7,5,2
Sholpan [36]

The "mean" of a group of numbers is also called their "average".

To calculate the mean, add up all the numbers, then
divide the sum by the number of items on the list.

Step #1:  Addum up:  3+7+2+9+4+7+3+7+5+2 = 49

Step #2:  Count the number of items on the list:  I count 10 .

Step #3:  Divide the sum by the number of items on the list.

                 49 / 10  =  4.9

The mean (average) of the numbers on that list is  4.9 .
