Two ladders are leaning against a wall at the same angle as shown. (The figure may not be drawn to scale.)
10
15 t
If the length of the shorter ladder and the distance from the wall to bottom of each of
the ladders are known, which of the following properties could be used to find the
length of the taller ladder?
O parallelism
None of the other answers are correct
similarity
O congruency
O perpendicularity

the correct answer is x/3+10≥32

hope this !

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

many reason,
