What he did was correct all the way up until he it 9. He forgot to add the negative sign in front of the 9. You are adding -4 and -5 together. You will get -9.
Answer:
58.0 units
Step-by-step explanation:
In order to use the law of sines, we need to know angle C. It will be the angle that brings the total of all angles to 180°.
C = 180° -A -B = 180° -72° -16°
C = 92°
The law of sines tells us ...
a/sin(A) = c/sin(C)
a = c·sin(A)/sin(C) = 61·sin(72°)/sin(92°)
a ≈ 58.0 . . . . units
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.
