Answer:
30 ft
Step-by-step explanation:
a² + b² = c²
(15sqrt(2))² + (15sqrt(2))² = c²
225 * 2 + 225 * 2 = c²
c² = 900
c = sqrt(900)
c = 30
Answer: 30 ft
To write the given phrase as an algebraic expression you can identify what does each part of the phrase mean:
59 less than: You have to substract 59 to the other part of the phrase
twice a number: as the number is n, twice a number is 2n
Then, you get the next algebraic expression:
You have
3/12 = x/16
Multiply by 16
16*(3/12) = x = 4
x = 4
