Answer:
<h2><u><em>
c</em></u></h2>
Step-by-step explanation:
100 degrees. 57 plus 23 equals 80, 180 minus 80 equals 100.
Answer:
4x(x^4-7)
Step-by-step explanation:
Option A, cos(57) = x/51
There's a really good mnemonic for remembering how trigonometry works: SOH CAH TOA
Sin = opposite/hypotenuse (SOH)
Cos = adjacent/hypotenuse (CAH)
Tan = opposite/adjacent (TOA)
In this scenario, we have to use cos(57) since 'x' is the adjacent side to the angle.
Since cos = adjacent/hypotenuse, we know that cos(57) = x/51.
Let me know if you need any further explanation.
