4^3 = 64
log4 64 = 3
The exponent always comes to the other side.
What is the question about ?? Is is asking the degree of the angle between 5 and 4 ?
4/5
Find common fractions of 12/15
12 / 15. each part divided by 3
15 / 3 = 5...12 / 3 = 4...12/15 = 4/5
Graph both equations on one coordinate plane. Wherever the equations intersect is your answer.
Okay so.
We have two basic equations
Tower A+ B+720 A is 720ft taller than B.
Tower A+B= 1982 Combined height is 1982ft
Replace A with B+720 in 2nd equation and solve for B
B+720+B=1982 Combine like terms
2B+720=1982 Subtract 720 from both sides
2B=1262 Divide both sides by 2
B=1262/2
B= 631ft
We know that A=B+720 so you simply need to do that addition to have the height of both towers.
