Answer:

Step-by-step explanation:

R means Rosa

given:

R+b+c=36

R R c-2=b, (R+2)+2=c

b-2=R, R+2=b

.

R+b+c=36 substitute for b and c

R+(R+2)+((R+2)+2)=36 add like terms

3R+6=36 subtract 6

3R=30 divide by 3

R=10

.

R=10

b=12

c=14

10+12+14=36

ollegr [7]

Answer:

The answer is 3) 40.

Step-by-step explanation:

since you're working with the Pythagorean theorem, you should know that a^2+b^2=c^2, therefore, we know that we only have two sides. we have a and c. we know that a = 42 and c = 58, giving us the equation of 42^2+b^2=58^2,

we want to find b!

so we would simply subtract the two.

58^2 - 42^2 = b

b = 1600

now we want to square root,

b = sqrt1600

which in the end, gives us the answer of 40.

The  dekameter (or decameter) first needs to be a translated into how many the meters. deka means 10, so a dekameter it must be 10 meters. So we have to divide 250 by 10, and then we will come up with 25 dekameters.
hope that helps!!
