Ok so basically I was absent for 3 days, now I have to do a quiz. So here are the questions.
(one with the picture that says something about coordinates)
There are 2 answers for each coordinate, for example "A=5, 5 "

What is the measurement of angle Y? (the triangle picture one)
The final question has the same picture as angle Y but the question is: "What is the scale factor that takes triangle XYZ to X'Y'Z?

75 degrees

Step-by-step explanation:

The angles of a triangle add up to 180 degrees. It doesn't matter if it is dialated or not, the angles will stay the same. 180 - (65+40) = 75 degrees.

75 degrees

Step-by-step explanation:

The angles of a triangle add up to 180 degrees. It doesn't matter if it is dialated or not, the angles will stay the same. 180 - (65+40) = 75 degrees.

answer: was that a question or answer?

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
