3.56 +/- 0.011 = ( 3.549, 3.571). This is the answer.
B, the bottom of the figure contains points E, F, and H
There are two triangles that exist in this problem. First is the given triangle ABC, witch AB = BC = 6 and AC = 8
Next is the smaller triangle formed by connecting points D and E; triangle EAD, with EA = AD = 3 and the length of DE is unknown.
Because these triangles are similar, a simple ratio may be set up in order to calculate DE.
DE / AC = EA / AB
DE = 3/6 * 8
DE = 4 units

Answer:
Cost of travel insurance for 4 days = 19 pounds
Step-by-step explanation:
The insurance company uses the formula T = 3.5n + 5 to work out the cost , T pounds for insuring the customer for n number of days . Where n is the number of days.
The algebraic equation given has two variables which are cost T of insuring and n which is the number of days for insuring. Mathematically,
T = cost of insuring in pounds
n = number of days
Therefore, finding the cost T for 4 days
T = 3.5n + 5
T = 3.5 × 4 + 5
T = 14 + 5
T = 19 pounds
Cost of travel insurance for 4 days = 19 pounds
