Answer:
RSU = 75.2°
Step-by-step explanation:
this is because:
⇒ RSU = RST + TSU
⇒ RSU = 48 + 27.2
⇒ RSU = 75.2°
Hence proved
So if we want to know the common solution(s) to a system of 2 equations, So we can just set both equations equal to each other and solve for the x value(s). That’s where I start below;
2x^2-13x+21 = 2x^2+9x-56
2x^2 cancels out and moving everything to one side and anything with an x variable to the other side we have then;
-22x=-77
22x=77 by cancelling the negative signs
x=77/22 therefore x=7/2 or 3.5
Hope this helps you. Any questions please ask.
