Answer:
78°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relations between angles and sides of a right triangle. In particular, ...
Cos = Adjacent/Hypotenuse
cos(F) = FG/FE = 1.5/7.5 = 0.2
The inverse cosine function is used to find the angle:
∠F = arccos(0.2)
∠F ≈ 78°
The answer would be true because a polynomial consists of many terms and a trinomial has three terms.
Answer: n is 3
Step-by-step explanation: n can only be 3 as a triangle is the only polygon whose internal angles have a sum of 180 degrees
