Answer:

a = 30

2a = 60

3a = 90

Step-by-step explanation:

3a + 2a + a = 180 ( Sum of angles of a triangle is 180)

6a = 180

a = 180/6

a = 30

2a = 2 x 30 =60

3a = 3 x 30 = 90

Flying with the wind, a plate went 251 km/h. Flying into the same wind, the plane only went 219 km/h. What is the speed of the w
Dennis_Churaev [7]

Answer: Option D, the actual speed of the wind is 16km/h.

Step-by-step explanation:

Let's define two quantities:

Sp = Speed of the plane, that we assume it is constant.

Sw = Speed of the wind, that we assume it is constant.

When the plane flies with the wind, the total speed will be

Sp + Sw = 251km/h.

When the plane flies against the wind, the total speed will be:

Sp - Sw = 219km/h.

Then we have two equations:

Sp + Sw = 251km/h

Sp - Sw =  219km/h.

We want to find the speed of the wind, so we should isolate the speed of the plane in one of the equations, let's isolate it in the second equation:

Sp = 219km/h + Sw.

Now we can replace this into the other equation:

Sp + Sw = 251km/h.

(219km/h + Sw) + Sw = 251km/h.

2*Sw + 219km/h = 251km/h

2*Sw = 251km/h - 219km/h = 32km/h

Sw = (32km/h)/2 = 16km/h.

This is really close to the option B, but is not equal, so the correct answer will be D, none of the above.
