Step-by-step explanation:
x+2+x=180
2x=180-2
2x=178
x=89
Let the width of table B be w, and since area of table A = area of table B, then 6 2/3 x 3 1/2 = 4 1/4 x w [this is the required equation]
20/3 x 7/2 = 17/4 w
17/4 w = 70/3
w = 70/3 / 17/4 = 70/3 x 4/17 = 280/51 = 5 25/51
Answer:
its B
Step-by-step explanation:
Answer:
angle FEA is 100°
angle AEC is 20°
angle CEG is 60°
Step-by-step explanation:
angle AEC=angle DEB=20°
angle AEG=angle FED=80°
80°-20°=60°; angle CEG=60°
angle FEA+angle AEC+ angle CEG=180°
angle FEA=100°
Answer:
9/20
Step-by-step explanation:
Total trials = 80
Observed successful trials = 36
36/80
= 9/20
