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''
A. True (plug in 0 for x to confirm y=-1)
b. True
c. True
d. False (If you plug in 1 for x, y would equal -2, not 2.)
Attached a solution and showed work.
I think its A 93 cm because when i work out the problem i get 93
