Answer: $15.25
Step 1: Multiply by 2 (for 2 steaks)
$6.10 x 2 = $12.20
Step 2: Find of $6.10 (for
pound)
$6.10 ÷ 2 = $3.05
Step 3: Add $3.05
$12.20 + $3.05 = $15.25
Answer = $15.25
Answer:
- a) 258 km
- b) 267°
- c) 87°
Step-by-step explanation:
- <em>Refer to attached diagram (not to scale).</em>
- <em>Given details are reflected.</em>
<u>First find the measure of angle Q</u>
- m∠Q = 36° + (180° - 125°) = 91°
a) <u>Use law of cosines to find x:</u>
- x = √(160² + 200² - 2160*200*cos 91°) = 258 km (rounded)
<u>Use the law of sines to find the missing angles:</u>
- 258 / sin 91 = 160 / sin R = 200 / sin P
- m∠R = arcsin (160 sin 91° / 258) = 38°
- m∠P = 180° - (91° + 38°) = 51°
b) <u>Bearing P from R:</u>
- 360° - (55° + 38°) = 267°
c) <u>Bearing R from P:</u>
- 36° + 51° = 87°
