In ΔKLM, the measure of ∠M=90°, the measure of ∠K=85°, and MK = 6.9 feet. Find the length of KL to the nearest tenth of a foot.

79.2

Step-by-step explanation:

If you are here from delta math this is the answer

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
