Answer:
2 23/50.
Step-by-step explanation:
2.46 = 2 46/100
= 2 23/50.
Step-by-step explanation:
By angle sum property
2x+10+4x-36+4x-34=180
10x -60=180
10x= 240
x=24°
Two angles are Complementary when they add up to 90°.
Therefore m∠DFG + m∠JKL = 90°.
We have m∠DFG = x + 1 and m∠JKL = x - 9. Substitute:
(x + 1) + (x - 9) = 90
(x + x) + (1 - 9) = 90
2x - 8 = 90 <em>add 8 to both sides</em>
2x = 98 <em>divide both sides by 2</em>
x = 49
m∠DFG = x + 1 → m∠DFG = 49° + 1° = 50°
m∠JKL = x - 9 → m∠JKL = 49° - 9° = 40°
<h3>Answer: m∠DFG = 50° and m∠JKL = 40°</h3>
I believe that the answer should be B.
y = 43.81 - .395x let y = 15....so we have
15 = 43.81 - .395x subtract 43.81 from both sides
-58.81 = -.395x divide both sides by -.395
x = about 149 mph
