Answer:
Step-by-step explanation:
<h3>Given</h3>
- m∠DXB = 70° 15' 12''
- m∠DXC = 30° 30' 20''
<h3>To find</h3>
<h3>Solution</h3>
<u>According to Angle Addition postulate:</u>
<u>Therefore</u>
- m∠CXB = m∠DXB - m∠DXC
- m∠CXB = 70° 15' 12''- 30° 30' 20'' = 39° 44' 52''
Answer:
Step-by-step explanation:
the multiplication property of zero,
if you multiply anything by zero the product will be zero
<span>Let x = # of rides
Plan A: 10 + 3x
Plan B: 20 + x
if x < 5 rides then plan A is better buy
if x = 5 both plans are the same
if x > 5 then plan B is the best buy
Prove:
x = 6 (rides)
plan A: </span>10 + 3x = 10 + 3(6) = 10+18 = $28
plan B: 20 + x = 20 + 6 = $26
