so to find angle one you just subtract the other angles from 180°

180°-33°-92°=55°

angle 2 is going to be equal to the adjacent angle every time so it's equal to 92°

angle 3 you just subtract everything from 360°

360°-90°-115°-92°= 63°

AXYZ has vertices at (0.0), (6,9), and (15.0).

exis [7]

Answer:

The coordinates of the vertices of the image are (0, 0), (2, 3), (5, 0) ⇒ (A)

Step-by-step explanation:

Let us talk about dilation

A dilation is a transformation that changes the size of a figure.
It can become larger or smaller, but the shape of the figure does not change.
The scale factor measures how much larger or smaller the image will be
If the scale factor greater than 1, then the image will be larger
If the scale factor between 0 and 1, then the image will be smaller

→ If point (x, y) dilated with scale factor m about the origin, then

→ Its image is (m x, m y)

Let us solve the question

∵ ΔXYZ has vertices:

→ X = (0, 0)

→ Y = (6, 9)

→ Z = (15, 0)

∵ ΔXYZ is dilated by a scale factor 1/3 about the origin

→ Multiply each coordinate in each vertex by the scale factor 1/3

∵ (0 × $\frac{1}{3}$ , 0 × $\frac{1}{3}$ )

∴ X' = (0, 0)

∵ (6 × $\frac{1}{3}$ , 9 × $\frac{1}{3}$ )

∴ Y' = (2 , 3)

∵ (15 × $\frac{1}{3}$ , 0 × $\frac{1}{3}$ )

∴ Z' = (5, 0)

∴ The coordinates of the vertices of the image are (0, 0), (2, 3), (5, 0)

Use circle C classify arc MNO in circle C

inna [77]

Answer:

Semicircle

Step-by-step explanation:

As we can see, the arc is bounded by the chord MO

since the chord passes through the center of the circle, we have it that the chord is a diameter

Mathematically, an arc bounded by a diameter represents half of a circle

So we can conclude that the arc MNO in circle C is a semicircle

What is the function y=2(x-4)^2-2 written in standard form

elena-s [515]

Answer:

$y = 2(x - 4) {}^{2} - 2 \\ y = 2x {}^{2} - 8 {}^{2} - 2 \\ y = {2x}^{2} - (8 \times 8) - 2 \\ y = {2x}^{2} - 64 - 2 \\ y = {2x}^{2} - 66 \\ \\$

3x + 8y = 28 3x + 2y = 4 Find both the x and y coordinates

umka2103 [35]

Answer:

(- $\frac{4}{3}$ , 4 )

Step-by-step explanation:

Given the 2 equations

3x + 8y = 28 → (1)

3x + 2y = 4 → (2)

Subtracting (2) from (1) term by term will eliminate the x- term

(3x - 3x) + (8y - 2y) = (28 - 4), that is

6y = 24 ( divide both sides by 6 )

y = 4

Substitute y = 4 into either of the 2 equations and solve for x

Substituting into (1)

3x + 8(4) = 28

3x + 32 = 28 ( subtract 32 from both sides )

3x = - 4 ( divide both sides by 3 )

x = - $\frac{4}{3}$

Solution is (- $\frac{4}{3}$ , 4 )
