So how do you go about doing these?

Mathematics

Sidana [21]3 years ago

For each of the problems for example #11 tells you to find the measure of angle ABC ABH=46 HBC=120
Therefore you just add the 2 together to get 166
So for #12 its a little diffrent the line is straight so it equals 180 degrees they give you one angle so 180-95= 85
Makes sense?

Answer:

x = 16

Step-by-step explanation:

The diagram can be misleading because angle A does not correspond to angle F. Rather angle F corresponds to angle C.

In congruent triangles, corresponding angles have the same measure. The sum of angles is always 180°, so we have ...

... m∠A +m∠B +m∠C = 180°

... (3x+6)° +50° +(9x -68)° = 180°

... 12x -12 = 180 . . . . . divide by °, collect terms

... x -1 = 15 . . . . . . . . . .divide by the coefficient of x

... x = 16 . . . . . . . . . . . add 1

_____

<em>Check</em>

m∠A = (3x+6)° = 54°

m∠C = (9x -68)° = 76°

The total of angles is 54° +50° +76° = 180°. . . . . as it should be

Use the drop-down menus to identify the method used to collect data for each scenario.
lianna [129]

The method used to collect data for each scenario is  observational study , secondary data , simulation  .

<h3>What is Data Collection ?</h3>

The accumulation of data to perform research , experiment or any other study is called data collection

It is done by different methods.

While standing in front of the school, Jace recorded the number of students who walked, rode their bikes, took the bus, and were driven there. :

Because all feasible channels and techniques were investigated in order to get accurate data, this study is known as an observational study.

Noah conducted research to learn the data pertaining to the proportion of newborns having brown eyes. Since he didn't perform this directly, it is referred to as secondary data.

Lara repeatedly flipped two coins to see how many times two heads appeared because she knew she had a 25% chance of winning a contest. This is an example of simulation because she wanted to see if she would come up with the same outcome.

Round each number  to the nearest tenth what is the best estimate for the answer to 38.94+65.43
mel-nik [20]
38.94 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down

38.94

The number is 4, so we round down. 38.94 becomes 38.9

65.45 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down.

65.43

The number is 3, so we round down. 65.43 becomes 65.4

38.9+65.4= 104.3

If you were to estimate 38.94+65.43, we round the number to numbers that we can easily calculate in our head. 38.94+65.43 becomes 40+65

40+65=105
