Let it be x

Using basic proportionality theorem

\\ \sf\longmapsto \dfrac{x}{10}=\dfrac{14}{7}

\\ \sf\longmapsto \dfrac{x}{10}=2

\\ \sf\longmapsto x=10(2)

Find the measure of the indicated angle to the nearest degree. Thanks.
Sholpan [36]

Answer:

θ ≈ 40°

Step-by-step explanation:

Since, sinθ = \frac{\text{Opposite side}}{\text{Hypotenuse}}

cosθ = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

tanθ = \frac{\text{Opposite side}}{\text{Adjacent side}}

In the picture attached,

Measures of adjacent side and opposite side of the triangle have been given. Therefore, tangent rule will be applied in the given triangle.

tanθ = \frac{19}{23}

θ = \text{tan}^{-1}(\frac{19}{23})

θ = 39.56

θ ≈ 40°

(5 + x)/6 = -1

Multiply both sides by 6.

5 + x = -6

Subtract 5 from both sides.

x = -11

What is the 6th value in the sequence with the explicit formula an=−2n−14?
Zinaida [17]

The 6th value in a sequence is -26.

<u>Step-by-step explanation</u>:

  • The formula for nth term is a sequence ⇒ an = -2n-14
  • To find 6th value in a sequence, substitute n=6 in the formula.

an = -2n-14

⇒ a6 = -2(6)-14

⇒ a6 = -12-14

⇒ a6 = -26

∴ The 6th value in a sequence is -26.
