If these two shapes are similar, what is the measure of the missing length a?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

idk

step-by-step explanation:

false

inverse variation is not exponential
