It’s D. 4 is the one next to X because that’s what is changing and -3 is the y intercept which comes after X
Answer:

Step-by-step explanation:
Let
x ----> the measure of one angle of the triangle
y ---> the measure of the second angle
z ----> the measure of the third angle
we know that
The sum of the measure of the interior angles in any triangle must be equal to 180 degrees
-----> equation A
One angle of a triangle measures 10 degrees more than the second
----> equation B
The measure of the third angle is twice the sum of the first two angles
---> equation C
substitute equation B in equation C

----> equation D
substitute equation D and equation B in equation A

solve for y

Find the value of x

Find the value of z

therefore

Answer:
radius is 8cm
Step-by-step explanation: radius is half of diameter so 16/2= 8
