Answer:

x° ≈ 50.0°

Step-by-step explanation:

The sides adjacent and opposite the angle are given. The appropriate trig relation is ...

Tan = Opposite/Adjacent

tan(x°) = 50/42

The inverse function is used to find the angle whose tangent is a particular value:

x° = arctan(50/42) ≈ 49.9697°

x° ≈ 50.0°

Step-by-step explanation:

<u>Step 1: Identify</u>

Angle θ = ∠R

Opposite Leg of ∠R = 10√3

Hypotenuse = 20

<u>Step 2: Solve</u>

Substitute in variables [sine]: $\displaystyle sin(R^\circ) = \frac{10\sqrt{3}}{20}$
[Equality Property] Trig inverse: $\displaystyle R^\circ = sin^{-1}(\frac{10\sqrt{3}}{20})$
Evaluate trig: $\displaystyle R = 60^\circ$

A submarine cruised below the surface of the water. During a training exercise, it made 6 dives, each time descending 35 feet mo

Brut [27]

Answer:

68 feet

Step-by-step explanation:

A submarine cruised below the surface of the water

During training exercise, each time descending= 45 feet

Number of dives= 4

Total distance he descended= 45×4 feet

Total distance he descended= 180 feet

Then, it rose by= 112 feet

Now , the distance he is at below the surface if water= 180- 112

The distance he is at below the surface if water= 68 feet

Now, he is at 68 feet below the surface of the Earth

Hence, the correct answer is 68 feet

An angle measures 12° less than the measure of its complementary angle. What is the measure of each angle?

ale4655 [162]

Let ∠1 be x

Let ∠2 be x-12

$\rm(x - 12 )+ x = 90 \degree$

$\rm2x - 12 = 90 \degree$

$\rm2x = 90 + 12$

$\rm2x = 102$

$\boxed{ \bf \: x = 51 \degree}$

$\sf \: ∠1 = x \\ \sf \: = 51 \degree$

$\sf \: ∠2 = x - 12 \\ \sf = \: 51 - 12 \\ \sf∠2 = 39 \degree$
