2. Find the value of x in the triangle. Round your answer to the nearest tenth of a degree. Show your work.

yarga [219]

Answer:

$\displaystyle 61,9° ≈ x$

Step-by-step explanation:

We have to determine which trigonometric ratio to use, depending on what is displayed for us, and we will be using the cotangent [or tangent] ratio, however, aside we are solving for an angle measure, we must use the inverse:

$\displaystyle cot^{-1}\: \frac{8}{15} ≈ 61,92751306° ≈ 61,9° \\ \\ OR \\ \\ tan{-1}\: 1\frac{7}{8} ≈ 61,92751306° ≈ 61,9°$

Extended Information on Trigonometric Ratios

$\displaystyle \frac{OPPOSITE}{HYPOTENUSE} = sin\:θ \\ \frac{ADJACENT}{HYPOTENUSE} = cos\:θ \\ \frac{OPPOSITE}{ADJACENT} = tan\:θ \\ \frac{HYPOTENUSE}{ADJACENT} = sec\:θ \\ \frac{HYPOTENUSE}{OPPOSITE} = csc\:θ \\ \frac{ADJACENT}{OPPOSITE} = cot\:θ$

What is the answer to triple a number is the s game as double the number increased by 5

kramer

Answer:

x = 7

Step-by-step explanation:

Let x = the number. Then

"Triple a number" means 3x

"is the same as" means =

"double the number increased by 5" means 2x + 7

∴ 3x = 2x + 7

Subtract 2x from each side

x = 7

The answer is x = 7.

Check:

3 × 7 = 2 × 7 + 7

21 = 14 + 7

21 = 21

OK.
