the sum of the angles in a triangle = 180°, thus

x + \frac{1}{2} x + \frac{1}{6} x = 180

multiply through by 6

6x + 3x + x = 1080

10x = 1080 ( divide both sides by 10 )

x = 108

the angles are 108°, 54° and 18°

Since all the angles are different and the largest is 108°

The triangle is an obtuse scalene triangle

2000 soldiers stand in a row. Beginning from the left, each soldier calls out a number, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, and
Cloud [144]

Answer:

The number of soldiers that call out a number 3 is 666 soldiers

Step-by-step explanation:

The parameters given are;

Number of soldiers = 2000

Soldiers calling from the left = 1, 2, 3,.....

Soldiers calling from the right = 1, 2, 3,.....

Therefore, since the number soldiers calling out the number 3 are 1 in 3 from the left and 1 in 3 from the right, we split the soldiers into 2 groups of 1000, with one group calling from left and the other group calling from the right;

The number of 3s in called out in the first group from the left is therefore;

1000/3 = 333.33 which is 333 soldiers  or from the 3rd soldier to the 999th soldier

Similarly the number of 3s called out from the second group = 333

Hence the total number of soldiers that call out a number 3 = 333 + 333 = 666 soldiers.

If a plant is planted and starts its height at 3 in and grows 2 in every week. when will the plant be 60 in tall?​
nadezda [96]

Answer:

28.5 weeks

Step-by-step explanation:

First, subtract 3 from 60:

60 - 3

= 57

Then, divide this by 2:

57/2

= 28.5

So, the plant will be 60 in tall after 28.5 weeks

Which graph represent f of x equals square root of the quantity x plus 2 end quantity minus 3? The graph shows a curve with an e
Svetach [21]

The graph of the function:

f(x) = \sqrt{x + 2} - 3

Is the last graph (bottom graph of the second image).  

<h3>Which graph represents the given function?</h3>

Here we have the function:

f(x) = \sqrt{x + 2} - 3

Remember that the argument of a square root must be zero or larger, then the minimum of the domain is the value of x such that:

x + 2 = 0

x = -2

Then the function starts at:

f(-2) = \sqrt{-2 + 2} - 3 = -3

Then the graph should start at (-3, 2).

We can also identify another point by evaluating in x = 2.

f(2) = \sqrt{2 + 2} - 3 =2 - 3 = -1

So the function also passes through (2, - 1).

Notice that the only graph that contains these two points is the last graph (the bottom graph on the second image), so that is the correct option.
