Answer:
Option B (35°).
Step-by-step explanation:
To solve this question, the trigonometric identity sin x = cos (90-x) is required. It can also be written as cos x = sin (90-x). It can be seen that this identity holds when the two angles are complementary i.e. they sum up to 90 degrees. Therefore, the answer can be determined by substituting all the options one by one in the identity cos x = sin (20+x). If x=30 degrees, then x+20=50 degrees. 30 and 50 are not complementary. If x=35 degrees, then x+20=55 degrees. 35 and 55 are complementary since their sum is 90 degrees. Therefore, B is the correct choice!!!
Answer:
below
Step-by-step explanation:
You've been asked to use specific x-values. Simply replace the x in the equation for each of your x-values then graph.
first equation!!

The formula is |(estimated - exact ÷ exact) x 100|
((15.375 - 15.125) / 15.125) x 100 = 1.652892562
You might want to round that number a 'lil
Part 2: She got 14.875 b/c with the equation there are no negative percentages, so that means that since 15.375 - 15.125 = 0.25, than 15.125-0.25 = what she got.
