To answer this you must know that all angles of a triangle have to add up to 180 degrees.

First, you have to write an equation to solve:

114 + 2y = 180

Simplify the equation:

2y = 66

Divide both sides by 2:

y = 33

The answer is B, 33 degrees

Answer: 57

Step-by-step explanation:

The sum of the two inside angles(y + y) , not neighbouring to the outside angle(114), equals to the outside angle) (114

Then

2 y = 114

Y = 57

What’s the correct answer

n200080 [17]

The third one would be the correct answer. I separately multiplied each number in the first section by each number in the second section. For instance, 0 x 2 is 0, 4 x 5 is 20, 5 x 3 is 15, and 2 x 0 is 0. All of these numbers are in the third answer.

Draw the image of △ABC under a dilation whose center is P and scale factor is 1/2

Vesna [10]

Answer:

Step-by-step explanation:

Let the point P is at the origin (0, 0).

Then the coordinates of A, B and C will be (8, 4), (-2, 2) and (4, -4) respectively.

Rule for the dilation of a point by a scale factor = k

(x, y) → (kx, ky)

If k = $\frac{1}{2}$

Then, A(8, 4) → A'(4, 2)

B(-2, 2) → B'(-1, 1)

C(4, -4) → C'(2, -2)

Now we can plot the new image with points A', B' and C'
