spin [16.1K]3 years ago
5 0

Answer:

see explanation

Step-by-step explanation:

∠AOB + ∠BOC = ∠AOC← substitute values

x + 3 + 4x - 7 = 2x + 11, that is

5x - 4 = 2x + 11 ( subtract 2x from both sides )

3x - 4 = 11 ( add 4 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

Thus

∠AOB = x + 3 = 5 + 3 = 8°

∠AOC = 2x + 11 = (2 × 5) + 11 = 10 + 11 = 21°

∠BOC = 4x - 7 = (4 × 5) - 7 = 20 - 7 = 13°

What is the tangent ratio for B
Ratling [72]

Answer:

C \frac{2}{1}

Step-by-step explanation:

Recall the mnemonics SOH-CAH-TOA

The tangent ratio is the ratio of the opposite side of the right triangle  to the adjacent side.

From the diagram, the side opposite to <B is 2 units and the adjacent side is 1 unit.

This implies that;

\tan \angle B=\frac{2}{1}

The correct choice is C

One minute after take off, an airplane altitude was 4,000 feet. Three minutes later , it was 20,000 feet what was the planes ave
Temka [501]

Answer:

The average altitude change of plane with time is 8,000 feet per min .

Step-by-step explanation:

Given as :

The initial height of plane after 1 min take off = 4,000 feet

The final height of plane after 3 min later = 20,000 feet

Let The rate of change of altitude in feet per min = s feet per min

Now, According to question

The change in altitude = final altitude - initial altitude

Or, D = 20,000 feet - 4,000 feet

I.e Distance change = 16,000 feet

The change in time = final time - initial time

Or T = 3 min - 1 min

I.e Time change = 2 min

Speed = \dfrac{\textrm Distance}{\textrm Time}

So, s = \frac{16,000}{2} feet per min

∴    s = 8,000 feet per min

So, Rate of change of altitude with respect to time = s = 8,000 feet per min

Hence The average altitude change of plane with time is 8,000 feet per min . Answer
