So a line is 180°
Since it gave you options, the easiest way would be to plug it in (plug and chug)
the answer is 11
first what I did was plug 12 into 5x+10 and then found the answer and then added 58°
the answer of that subtracted from 180
with that I then plugged in 11 for x for 11x+2 = 123
180 - 123 = 57 which is the same answer for the missing angle within the triangle
Answer:
Step-by-step explanation:
First your going to plug in what p and q are into the equation so 3(2)^5+10(-3)^2 over 7(2)+1.
Your going to first do (2)^5 and (-3)^2 so it’s going to be 3(32)+10(9) over (multiply the 7(2) first) 14+1.
3(32)+10(9) over 14+1 now multiply 3(32) and 10(9) you should get (96)+(90) over 15.
add 96+90 to get 186 over 15.
then divide how many times 15 can go into 186 you should get 12 6/15 and divide 6/15 by 3 to get your final answer 12 2/5.
I hope this helps!

Answer:
True; about 120° CCW rotation about Q
Step-by-step explanation:
Triangle A'B'C' appears to be congruent to triangle ABC and about the same distance from point Q. The angle of rotation from ABC to A'B'C' appears to be about 120° counterclockwise when measured using a geometry program.
Triangle A'B'C' is the image of triangle ABC under rotation about 120° CCW about point Q.

<em>Additional comment</em>
If choices of rotation angle are ±135° or ±165°, the best choice would be ...
135°
Step-by-step explanation:
the answer is:
x=180-90-70=20°
