In the figure, the measure of angle 7 is 57°. What is the measure of angle 8?

pochemuha

Angle (6) + Angle (7) = 180

Angle (6) + 57 = 180

Angle (6) = 180 - 57

Angle (6) = 123

------------

Angle (6) = Angle (8)

-----------

Therefore:

Angle (8) = 123 degrees

Answer:

tan(θ) = 0, 0.577, -0.577

Step-by-step explanation:

3tan³(θ) - tan(θ) = 0

tan(θ)(3tan²(θ) - 1) = 0

tan(θ) = 0

tan²(θ) = ⅓ tan(θ) = +/- sqrt(⅓)

tan(θ) = 0, sqrt(⅓), -sqrt(⅓)

tan(θ) = 0, 0.577, -0.577

To find θ values, domain is required

Answer:

The distance is 280 miles

Step-by-step explanation:

Given

When going to the mountain:

Let the speed be x.

$Speed = x$

$Time = 8$

When going home:

$Speed = 21 + x$

$Time = 5$

Required

Determine the distance of the mountains

Distance is calculated as:

$Distance = Speed * Time$

When going to the mountains, the distance is:

$Distance = x * 8$

When going home, the distance is:

$Distance = (21 + x) * 5$

It should be noted that, the distance is the same.

So, we have:

$x * 8 = (21 + x) * 5$

Open bracket

$x * 8 = 21* 5 + x * 5$

$8x = 105 + 5x$

Collect Like Terms

$8x - 5x= 105$

$3x= 105$

Divide both sides by 3

$x= \frac{105}{3}$

$x= 35$

Substitute 35 for x in

$Distance = x * 8$

$Distance = 35 * 8$

$Distance = 280$

The distance is 280 miles
