A triangle has angles measuring 15° and 45°. What is the measurement of the triangle’s third angle?

2 answers:

First you need to know that the internal angles of a triangle always equals 180°. Therefore:

15+45= 90°

Then since the angles should equal 180, you do:

180-90=90

So the missing angle equals 90°

Answer:

Slope of the line DV = -1

Step-by-step explanation:

Let point D (-5, 1) be $(x_{1}, y_{1})$

Let point V (-1, -3) be $(x_{2}, y_{2})$

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in the appropriate values,

$m = \frac{-3-1}{-1-(-5)} = \frac{-4}{4} = -1$

slope equals -1

Hi this is for texaschic101 mainly but anyone else is fine too.

Makovka662 [10]

Because the two angles on the right add to 180 degrees, we can create this system:

$(2x + 25) + y = 180$

We can also prove that $3x = 2x + 25$ , which, when solved, shows that $x = 25$ .

When plugged in to the original equation, we find that y = 105 degrees.

Two number cubes are rolled.

hichkok12 [17]

Answer:

When two number cubes are rolled,

Sample space= Total Possible outcome {11,22,33,44,55,66,12,21,13,31,14,41,15,51,16,61,23,32,24,42,25,52,26,62,34,43,35,53,36,63,45,54,46,64,56,65}=36

Probability of an event = \frac{\text{Total favorable outcome}}{\text{Total possible outcome}}

Sum of 4 is obtained when ={13,31,22}=3

Probability of getting 4 when 2 number cubes are rolled= \frac{3}{36}=\frac{1}{12}

Sum of the numbers is greater than 9= 10, 11,12={55,64,46,56,65,66}=6

Probability of getting(Sum of the numbers is greater than 9)=\frac{6}{36}=\frac{1}{6}

1. Determine if the set of ordered pairs is a relation or a function.

kykrilka [37]

Answer:

This is just a relation.

Step-by-step explanation:

It is easy to see if a set of ordered pairs is a relation or a relation that is a function.

If all the points are distinct, then you just have to look at the $x$ -coordinates.

If all the $x$ -coordinates are different, then it is a function. Otherwise, it is a just a relation.

So this cannot be a function because there is at least two different points that have $x=0$ .
