The equation tan(55°)= 15/b
can be used to find the length of ac
what is the length of ac? round to the nearest tenth.

10.5

Step-by-step explanation:

tan(55°)=15/b

b=15/tan(55°)

=10.5

AC ≈ 10.5

Step-by-step explanation:

tan55° = = =

Multiply both sides by b

b × tan55° = 15 ( divide both sides by tan55° )

b = ≈ 10.5

Hence b = AC ≈ 10.5 ( to the nearest tenth )

215.92 dollars is the answer

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
