Answer:

x=33 (since it says to round it)

Step-by-step explanation:

This is an ASA triangle.

First, we need to find the value of the unlabeled angle, which is simple:

180°-70°-76°=34°  Lets call that angle A

Now we use the law of sines:

x/sinX = a/sinA

x/sin76° = 19/sin34°

Then:

x = (19/sin34°) × sin76°

x = 32.968

Answer:

x ≈ 33.0

Step-by-step explanation:

The third angle in the triangle is

180° - 70° - 76° = 180° - 146° = 34°

Using the Sine rule in the triangle

\frac{x}{sin76} = \frac{19}{sin34} ( cross- multiply )

x × sin34° = 19 × sin76° ( divide both sides by sin34° )

x = \frac{19sin76}{sin34} ≈ 33.0 ( to the nearest tenth )

Y=sech(tan‐¹x) find the derivative ​
Klio2033 [76]

Recall that

d/dx sech(x) = - sech(x) tanh(x)

d/dx tan⁻¹(x) = 1/(1 + x²)

Then by the chain rule,

dy/dx = - sech(x) tanh(x) / (1 + x²)

Stels [109]

Answer:

Step-by-step explanation:

This is a geometric mean problem...a ratio. The geometric mean is the height of the triangle, 6. To solve:

\frac{x}{6} =\frac{6}{3} and cross multiply to solve for x:

3x = 36 so

x = 12
