Answer:

27 feet

Step-by-step explanation:

Total distance from base of lamp to tip of shadow

15 + 8 = 23

-------------------------

tan∅ = opp/adj

opp will be the height of the lamp

adj is 23

--------------------------

tan 50 = opp/23

multiply both sides by 23

23 * tan50 = opp

Use calculator

27.4 = opp

Rounded

27 feet

S=(l)(b)(b) solve for s
Alona [7]
I’m not entirely sure but i think it might be s=lb^2 because the l, b, and b are all being multiplied together, and since you are multiplying and not adding the b’s, the two would go to b^2, and then you just multiply by l to get lb^2

7 times a number equals 3 less than 5 times that number. what is the number?
inessss [21]

First the equation would look like this:

7n = 5n - 3

7n - 5n = 5n - 5n - 3   -Subtract 5n from both sides.  Which gives you...

2n = -3      

2n/2 = -3/2          -Divide both sides by 2

n = -1.5

Hope this helps!
