Answer:
coefficient of x: 2
coefficient of y: 3
coefficient of z: -7
Step-by-step explanation:
To solve this problem, first we need to sum the polynomials A and B, then we need to check the coefficients of x, y and z.
The sum of the polynomials is:
A + B = 5z + 4x^2 - 6y + 2 + 2x + 9y - 12z - 2
A + B = 4x^2 + 2x + 3y - 7z
So, the coefficients are:
coefficient of x^2: 4
coefficient of x: 2
coefficient of y: 3
coefficient of z: -7
The measure of arcPR and arcRPT are 83 and 208 degrees respectively
The measure of arc ST will be gotten using the expression below:
arcPS = arcPT + arcST
Given the following
arcST = arcPS - arcPT
arcST = 180 - 125
arcST = 55 degrees
Similarly, arcPR = 180 - arcRS
arcPR = 180 - 97
arcPR = 83 degrees
arcRPT = arcPR + arcPT
arcRPT = 83 + 125
arcRPT = 208 degrees
Hence the measure of arcPR and arcRPT are 83 and 208 degrees respectively

Answer:
A)dilation
Step-by-step explanation:
The transformation preserves only angle measurement is dilation. The transformation helps in taking up the production of an image that is of the same shape as the main original image.
