The sum of the interior triangles in a triangle is 180, so if we add all the angle measures together, we should get 180. Therefore, we can make an equation like this,

$110-2x+x+50+5x-40=180$

Simplify this.

$4x+120=180$

$4x=60$

$x=15$

Now we can find each angle measure.

$110-2x$

$110-2(15)$

$110-30$

$80$

$x+50$

$15+50$

$65$

$5x-40$

$5(15)-40$

$75-40$

$35$

So the angle labeled $110-2x$ is the largest angle in the triangle.

Scientific notation of 0.000125

tester [92]

Answer:

1.25 × 10^-4

Step-by-step explanation:

Move the decimal until it's at 1.25. You had to go right 4 times so it's negative. If it were 12500 then you'd do it until it was 1.2500 which would be going left so it'd be a positive 4

On a test that has a normal distribution, a score of 49 falls two standard deviations below the mean, and a score of 61 falls on

Zolol [24]

The mean of this test will be 57.

<h3>What is Standard Deviation and Mean?</h3>

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

The mean can be used to get an overall idea, or picture, of the data set.

Let Mean be 'm'

and standard deviation= $\sigma$

So, m-2 $\sigma$ =49

and, m + $\sigma$ =61

Solving the above two equation we get

$\sigma =4$

Now, m= 61- $\sigma$

= 61-4

= 57

So , the mean of this test will be =57

What is 3 and 1 tenth as a desimal

Bess [88]

Representing 3 and one tenth as decimal by 3.1

<u>Step-by-step explanation:</u>

Here 3 is the whole number.

1 tenth is nothing but $\frac{1}{10}$ .

$\frac{1}{10}$ = 0.1

When we write numerals with tenths using the decimals we can use a decimal point also the tenths positioned to the right of the decimal point. The tenth place is denoted as immediately right to the decimal point.

So it is represented as 3.1.
