Answer:
5.0587
Step-by-step explanation:
"four decimal places" would be the numerals 0587. Since that 7 is followed by a zero, we round off 5.05870925358 to 5.0587. This is "to 4 decimal places."
Answer:
Step-by-step explanation:
<h2>1</h2>
Use similarity ΔPQS ~ ΔRQS
<u>Use the ratio of corresponding sides:</u>
- PS/QS=QS/SR
- PS*SR = QS²
- PS*20 = 8²
- 20PS = 64
- PS = 64/20
- PS = 3.2
<h2>2</h2>
Find PS
- PS = PR - RS = 72 - 54 = 18
Use similarity ΔPQS ~ ΔPRQ
<u>Ratio of corresponding sides:</u>
- PQ/PR=PS/PQ
- PQ² = PR*PS
- PQ² = 72*18 = 4*18*18 = (2*18)² = 36²
- PQ = 36
<h2>3</h2>
Use similarity ΔPQS ~ ΔPRQ
<u>Ratio of corresponding sides:</u>
- PQ/PR=PS/PQ
- PS=PQ²/PR
- PS = 14²/28 = 7
<u>Find RS:</u>
- RS = PR - PS = 28 - 7 = 21
<h2>4</h2>
<u>Answer options</u>
- a) ΔRPQ ~ ΔRQS - correct
- b) ΔRQS ~ ΔQPS - correct
- c) ΔRPQ ~ ΔQPS - correct
- d) ΔRPQ ~ ΔRQS ~ ΔQPS - most correct as combines all above choices
