Answer:
sin O = 
Step-by-step explanation:
given tan O =
= 
Then this is a right triangle with legs 3 and 4
Using Pythagoras' identity then the hypotenuse (h ) is
h =
=
= 5, hence
sin O =
= 
We will solve the problem for both cases:
Case 1:
If the amount increases by 7% we have the number for which we are going to multiply is given by:


Case 2:
If the amount decreases by 7% we have the number for which we are going to multiply is given by:


Answer:
single multiplier you would use for each case is:
x = 1.07 (increase)
x = 0.93 (decrease)
The answer for this question would be
B) Identify property of multiplication or the second option because since the result 20 is the same as the 20 multiplied against 1. * I take no credit for the image below I just found it off google. ✅
