The "SOH" in "SOHCAHTOA", the acronym for correlating the sin, cosin, and tangent to places in a triangle, represents what?

• Sin = Opposite/Hypotenuse

• Sin =

  Opposite + Hypotenuse

• Sin =

  Hypotenuse/Opposite

• Sin =

  2(Hypotenuse x Opposite)

The "CAH" in "SOHCAHTOA", the acronym for correlating the sin, cosin, and tangent to places in a triangle, represents what?

• Cos =

  Adjacent x Hypotenuse

• Cos =

  Adjacent/Hypotenuse

• Cos =

  Adjacent + Hypotenuse + 180

• Cos =

  Hypotenuse/Adjacent

The "TOA" in "SOHCAHTOA", the acronym for correlating the sin, cosin, and tangent to places in a triangle, represents what?

• Tan =

  Opposite / Hypotenuse

• Tan =

  Opposite + Hypotenuse

• Tan =

  Opposite/Adjacent

• Tan =

  2(Opposite/Adjacent) + 180

If the cosine of A is 4 degrees, solve for the missing side.

(answer explanation if you get it wrong)

• 585

• 220

• 52

• 23

Answer explanation

To find the answer, use SOH CAH TOA to find the missing side, or x. the cosine is equal to the adjacent/hypotenuse.

Solve for x and you'll find the answer.

Solve for A, assuming the tan of 35 equals 0.5

• 4

• 8

• 9

• 6

Answer explanation

To find the answer, use SOH CAH TOA to find the missing side, or x. the tangent is equal to the opposite/adjacent.

Solve for x and you'll find the answer, 12.

x/12 = 0.5

x = 0.5 x 12

0.5 x 12 = 6

x=6

We can use SOH-CAH-TOA for...

• Any triangle ever
• Non-right triangles only
• Right Triangles only
• Never

assuming the sin of 53 = 0.4,

find x

(answer explanation if you get it wrong)

• 3

• 6

• 12

• 2

Answer explanation

SOH = Sin = opposite/hypotenuse

0.4 = x / 15

0.4 x 15 = x

x = 6
