In triangle ABC, angle A measures 33 degrees and angle C measures 122 degrees. What is the measure of angle B?

Answers

Answer:

∠ B = 25°

Step-by-step explanation:

the sum of the three angles in a triangle = 180° , that is

∠ A + ∠ B +∠ C = 180° ( substitute values for A and C )

33° + ∠ B + 122° = 180° , that is

155° + ∠ B = 180° ( subtract 155° from both sides )

155° - 155° + ∠ B = 180° - 155° , that is

∠ B = 25°

Rewrite this expression using the distributive property then simplify.
2/3(6x+12)

Answers

so distributive property of multiplication says
a(b+c)=(ab)+(ac)

so 2/3(6x+12)=((2/3)6x)+((2/3)12)=12/3x+24/3=4x+8=4(x+2)
2/3(6x+12)

=12/3x+24/3

=4x+8

20 yards 8 inches is divided into 26 equal sections, how long is each section

Answers

In the given question, there are several information's of immense importance and worth taking a look. based on these information's, the answer to the question can be easily determined.The length that has to be divided into 26 equal parts is 20 yards and 8 inches.Firstly we have to change the yard into inches and then we can divide the total inches into 26 equal parts.
We know
1 yard = 36 inches
20 yards = 720 inches
Then the total length that has to be divided = (720 + 8) inches
                                                                     = 728 inches
Now we have to divide the 728 inches into 26 equal parts.
Length of each section = (728/26) inches
                                      = 28 inches.
So each of the 26 parts will have a length of 28 inches.

Determine the coordinates of
triangle A'B'C'.

Answers

Using translation concepts, the coordinates of triangle A'B'C' are given as follows:

A' (11, 12), B' (5,-10), C (-2, 2).

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis, or rotations of a degree measure around the origin.

For this problem, the translation rule is given as follows:

(x,y) -> (x + 3, 2y).

Applying the rule to each vertex, we have that:

  • A': (8 + 3, 2(6)) = (11, 12).
  • B': (2 + 3, 2(-5)) = (5, -10).
  • C': (-5 + 3, 2(1)) = (-2, 2).

Hence the coordinates of triangle A'B'C' are given as follows:

A' (11, 12), B' (5,-10), C (-2, 2).

Final answer:

The transformed coordinates of triangle ABC using the rule (x,y) - (x + 3,2y) are A' (11,12), B' (5,-10), and C' (-2,2).

Explanation:

To solve the problem, we apply the given transformation rule (x,y) - (x + 3,2y) to each vertex of triangle ABC. Thus, vertex A (8,6) will transform into A' (8+3,2*6), B (2,-5) will become B' (2+3,2*-5), and C (-5,1) will transform into C' (-5+3,2*1). Let's calculate:

A'(8+3, 2*6) = A' (11,12). B' (2+3, 2*-5) = B' (5,-10). C' (-5+3, 2*1) = C' (-2,2)

So, the coordinates of triangle A'B'C' after the transformation are A'B'C': A' (11,12), B' (5,-10), C' (-2,2).
