Answer:
x = 50°
Step-by-step explanation:
130 and x are adjacent angles on a straight line and sum to 180° , so
x + 130° = 180° ( subtract 130° from both sides )
x = 50°
Sorry but I’m lost what are you talking about
Based on function transformations, the graph of y= cos(2θ), is the same as the graph of <span>y= cos(θ), with a component B of 2, in which case, it means the period is the only thing that differs
well the period for this function will then be </span>

so, the graph of is, the same as y= cos(θ), just shrunk by half horizontally
The answer for this question would be
B) Identify property of multiplication or the second option because since the result 20 is the same as the 20 multiplied against 1. * I take no credit for the image below I just found it off google. ✅
