Help me pls I’m stuck

44

Step-by-step explanation:

<R is an inscribed Angle- so if we follow it's ends to the intercepted Arc we are looking at arc NQ

the intercepted arc is 2 times the measure of the inscribed angle, so arc NQ is 44 (22*2)

<O has the same measure as the arc  NQ so angle O is 44

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

abde or 1,2,4, 5 is the answer
