∠ R ≈ 39°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos R = \frac{adjacent}{hypotenuse} = \frac{RS}{QR} = \frac{61}{78} , then

∠ R = cos^{-1} (\frac{61}{78} ) ≈ 39° ( to the nearest degree )

A geologist noticed that a land along a fault line moved 24.8 centimeters over the past 175 years . On average, how much did the
olasank [31]

Answer:

On average, the land moved 0,14 cm each year.

Step-by-step explanation:

To know how much did, on average, the land move,  we should divide the total number of cm over the total number of years:

x=24.8 cm/175 years

x=0,1417 cm each year

If we divide years over cm we will get x in years each cm, which is wrong.

Because the problem asks for the answer rounded to the hundredths place:

x= 0,14 cm each year

NNADVOKAT [17]

Given data:

The first point given iis (a, b)=(-6,2).

The second point given is (c,d)=(0, -6).

The expression for the slope is,

m=(d-b)/(c-a)
