Question 10(Multiple Choice Worth 4 points) (01.02 LC) Which of these is a correct step in constructing congruent angles? Use a straightedge and draw an arc across the first arc from a leg of the given angle.

Use a straightedge to measure the width between the points where the first arc cuts both legs of the given angle.

Use a compass and draw an arc across both the legs of the given angle.

Use a compass and join points to make the new leg of the congruent angle

can i see the following ?

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
