Answer:

4.58

Step-by-step explanation:

21 is not a perfect square, but lies between the perfect squares 16 and 25. Thus, √21 lies between √16 and √25, that is, between 4 and 5. Since 21 is closer to 25 than to 16, √21 is closer to 5 than to 4. A rough estimate of √21 would be 4.7.

√21 done on a calculator comes out to 4.58.

Answer:

steps below

Step-by-step explanation:

arc QR = 2x57 - 41 = 73

arc PQ = 360 - 73 - 41 - 137 = 109

m∠Q = (41+137) / 2 = 89°

m∠R = (109+137) / 2 = 123°

m∠S = (109+73) / 2 = 91°

check: ∠R+∠p = 123+57 = 180

∠Q+∠S = 89+91 = 180
