Complimentary angles have a sum equal to 90° If. 21 = 3x - 5
If. 22 = x + 7
Using the picture below, identify the measure of 21 and 22.
1
2
O The measure of Z1 = 22° and the measure of 2 = 68º.
The measure of Z1 = 29° and the measure of 2 = 61°
O The measure of Z1 = 68° and the measure of 22 = 22°
The measure of 21 = 61º and the measure of 22 = 29

Ummm there's no picture so I kinda cant answer

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
