A teacher asks three different students to draw a triangle with the angles 30o, 70o, and 80o. If they draw the angles correctly,

which statement is true about the three angles drawn?
a The triangles do not have to be congruent because the side lengths are not given, so the angle measurements can form many different angles.

b The triangles must be the same size and shape because 30o+ 70o > 80o, which makes a unique triangle.

c There is not enough information to draw any conclusions about the relationship between the triangles the students draw because the drawings are not given.

d The triangles must be congruent because the three angle measurements add up to 180o, which makes a unique triangle.

Answer:

∠ XZY ≈ 23.6°

Step-by-step explanation:

Using the sine ratio in the right triangle, that is

sinXZY = \frac{opposite}{hypotenuse} = \frac{XY}{YZ} = \frac{6}{15} , then

∠ XZY = sin^{-1} (\frac{6}{15} ) ≈ 23.6° ( to 1 dec. place )

Which ordered pair in the form (a, b) is a solution of this equation?
Evgen [1.6K]

3a - 4b = 21


check (-2 , -3)


3(-2) -4(-3) =21


-6 +12  = 21


6 does not = 21  so NO


check (0 , 7)


3(0) -4(7) =21


0-28=21


-28 does not equal 21  so NO


check (-3 , -2)


3(-3) -4(-2) =21


-9 +8  = 21


1 does not = 21  so NO


check (7 , 0)


3(7) -4(0) =21


21  = 21

A minor-league hockey team had the following scores for the start of the season: 3, 6, 2, 1, 2, 3, 0, 4, 5, 1, 5, 4.

If the hockey team scores 9 goals in their next game, it means that; the mean would be the most affected.

<h3>How to find mean, median and mode?</h3>

We are given the data set as;

3, 6, 2, 1, 2, 3, 0, 4, 5, 1, 5, 4.

Let us rearrange in ascending order to get;

0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6.

The mean = (0 + 1 + 1 + 2 + 2 + 3 + 3 + 4 + 4 + 5 + 5 + 6)/12 = 3

Median = (3 + 3)/2 = 3

Mode = 1, 2, 3, 3, 5

Now, if they score 9 goals in their next game, it means that;

Mean = 45/13 = 3.46

Median = 3

Mode remains the same

Thus, mean will be the most affected.
