Because of the parallel lines, angles A and DCE are congruent.
Also, angles E and BCA are congruent.
That makes angles B and D congruent.
m<DCE = 70 and m<EDC = 50, so m<E = 60
m<BCA = m<E = 60
Assuming the number is 331/2, or 331 over 2:
331/2 = 165.5 ÷ 400 = .4138 x 100% = 41.38%
100% - 41.38% = 58.62% not nickels
If the number is 33 1/2, or 33 and one half
33 1/2 = 67.5 ÷ 400 = 0.0838 x 100% = 8.38%
100% - 8.38% = 91.62% not nickels
Answer:
Slope: 1/3
Step-by-step explanation:
y = 1/3 x - 2
1. Find the difference ( diff is 2 )
2. Apply the concept diN+0 (more easier use this :) )
* di is difference
* N is nth term
* 0 is first term - difference
3. Find 0
- first term (2) - difference (2) = 0
answer: 2n
