In the figure, x is an exterior angle to the triangle below. a) Explain why x is equal to the sum of the measures of the two nonadjacent interior angles. You need to present the equation with step /work that proves this theorem.

b) what is the measurement of ≤x

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

x

step-by-step explanation:

yes

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
