Help me please and thank you

x = 27

Step-by-step explanation:

<5  and <6 are supplementary angles so they add to 180

<5 + <6 = 180

3x-32 + 131 = 180

Combine like terms

3x +99 = 180

Subtract 99 from each ide

3x+99-99= 180-99

3x= 81

3x/3 = 81/3

x =27

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

answer: 8
