Angles A and B are complementary. What is the value of x? 34 56 68 79
Lelu [443]

Answer: x = 34°


Explanation:


As per definition, complementary angles add up 90°.


In the figure you see angle A measures x + 22° and angle B measures x.


Therefore, according to the definition, you can set this equation:

       

             x + 22° + x = 90°


Solve for x:


  • start: x + 22 + x = 90
  • combine like terms: 2x + 22 = 90
  • subraction property: 2x = 90 - 22
  • do the operation: 2x = 68
  • division propery: x = 68/2
  • do the operation: x = 34

Answer: x = 34°

Write a function rule for the table.
Pavlova-9 [17]
The correct answer is:  [C]:  " p = 6.25 h " .
______________________________________________________
Explanation:  
______________________________________________________

It is clear that "pay" is a function of "hours worked" ; 

So, we can eliminate:  "Choice [B]:  " h = <span>6.25p" .
______________________________________________________
Try, Choice [A]:  " </span>p = h + 12.5 " ; and 14.50 ≠ 12.50 ; (12.50 is the amount shown in the table.  So, we can already eliminate "Choice [A]".
<span>_____________________________________________
Now that we have eliminated choices [A] and [B]; 

we are left with choices:  [C] and [D]:
_____________________________________________
Consider choice [C]:  " </span><span>p = 6.25h " ;  
</span>   when "h = 2" ; does: "p = 12.5" (as shown on table)?? ; 

i.e. " 12.5 =? 6.25 * (2) ?? Yes!  This choice is a POSSIBILITY.
_____________________________________________
Consider choice [D]:  " p = 12.5h" .

When "h = 2, does "p = 12.5" (as shown on table)?  No!  
   → We can see from this very answer choice
        (the equation itself) that when "h = 2" ;
the value of "p" is DOUBLE [that of "12.5"].
 ________________________________________________
The correct answer is:  Answer choice:  [C]:   " <span>p = 6.25 h " .
