Question 1
In a right triangle, sin(theta) =
- A) opposite/adjacent
- B) opposite/hypotenuse
- C) adjacent/hypotenuse
- D) hypotenuse/opposite
Show answer
Answer: opposite/hypotenuse
SOH-CAH-TOA: Sin = Opposite/Hypotenuse; Cos = Adjacent/Hypotenuse; Tan = Opposite/Adjacent. (Theta = the angle.)
-
Question 2
cos(60) = ?
- A) 1/2
- B) sqrt(3)/2
- C) 1
- D) 0
Show answer
Answer: 1/2
Special angles: cos(0)=1, cos(30) = sqrt(3)/2, cos(45) = sqrt(2)/2, cos(60) = 1/2, cos(90)=0.
-
Question 3
In a right triangle, opposite=3, hypotenuse=5. sin(angle)?
- A) 3/5
- B) 5/3
- C) 4/5
- D) 3/4
Show answer
Answer: 3/5
SOH: sin = opposite/hypotenuse = 3/5 = 0.6.
