Answer:
2 2/5 inches
Step-by-step explanation:
3/5 x 4
3/5 x 4/1
3/5 x 4/1 = 12/5
12/5 = 2 2/5
Answer:
x = 40°
Step-by-step explanation:
Two sides are the same length, so the angles opposite them are the same size.
The sum of the angles = 180°. One angle is 100°, so the sum of the remaining two angles is 80°.
Since the remaining two angles are congruent, each is 40°.
To answer this problem, you need to use SOHCAHTOA. The pole, the tent, and the ground form a right triangle. One leg is equal to 5. The top angle is 55. You need to find length of the other leg, so use tangent.
tan55=O/5
O=0.4375
Double this to find the total width of the tent. 0.4375*2=0.875
0.875 (rounds to 1) feet
Hope this helps!!
(y - 4)(y^2 + 4y + 16) = y^3 + 4y^2 + 16y - 4y^2 - 16y - 64
Therefore, a = 16.
