He is not correct. If this is to be an equilateral triangle then all the angles must be the same measure. That means that 180/3 = 60°. They all have to equal 60°. If one of the angles measures 4x-12, then 4x-12=60. Solving for x, we will add 12 to both sides to get 4x=72. x here is 18. For the other angle measuring 2x+26, we would do the same. 2x+26=60. Subtract 26 from both sides to get 2x= 34 and x = 17. He was way off.

Answer:
The answer would be A. 55.
Step-by-step explanation:
For the 35% you would take your 200 and divide it by 2 and have two 100's. Since 35% is out of 100% you could take 35 from each 100 and add them together to get 70.
For the 3/8 you would divide and get .375 then you would multiply that by 200 which would give you 75 yellow tags. Then you would add 75 and 70 and get 145. Then subtract 145 from 200 to get 55. Therefore there would be 55 red tags.
<span>Given the question "If 9i is a root of the polynomial function f(x), which of the following must also be a root of f(x)?" The correct answer is -9i.
Given a polynomial with a complex root, then the conjugate of the complex root must also be a root to that polynomial function.
The conjugate of a complex number is the number with equal real part and imaginary part but with the sign between the real part and the imaginary part opposite. For example, the complex conjugate of 3 + 4i is 3 − 4i.
Therefore, given that 9i is a root to a polynomial function f(x), the conjugate of 9i = -9i will also be a root to the equation.</span>
