Answer:

We are given that the sum of the measures of angles A and B is equal to the sum of the measures of angles B and C. The measure of angle B is equal to itself by the reflexive property, so you can subtract that measure from both sides of the equation. Now the measure of angle A equals the measure of angle C. By the symmetric property, this means the measure of angle C equals the measure of angle A.

What number falls between √60 and √75

Natalija [7]

To find the number halfway between 60 and 75, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 60 and 75 into our formula, we get:

(60 + 75)/2 = 67.5

Thus, the number halfway between 60 and 75 is 67.5.

The numbers of pages in the books in a library follow a normal distribution. If the mean number of pages is 180 and the standard

laiz [17]

Answer:

option B.

About 16% of the books have fewer than 150 pages

Step-by-step explanation:

Since we are dealing with a normal distribution

68.27% of the values will fall in the range with the standard deviation

(180-30 , 180+30) = (150, 210)

Approximately 15.86% of the values will be higher than 210

and the rest 15.86% will be lower than 150

So the correct answer is option B.

About 16% of the books have fewer than 150 pages

Please help it’s for geometry

vredina [299]

Answer:

x=25

Step-by-step explanation:

they are supplementary and adjacent, thus you do 4x-3+3x+8=180, simplify and get 7x+5=180, subtract 5 from 180 which is 175, then ending up with 7x=175 and 175/7 is 25.
