Grace has a 45 degree upwards angle, then the height of the lighthouse is 14'.
Case A. Kelly is 26 feet from the lighthouse.
The arcTangent of 14/26 is a 28.3 degree angle.
Case B. But if Kelly stood closer to the lighthouse, i.e. 2 feet away, then her angle is arcTangent of 14/2 = 81.9 degrees
Answer: 7/8
Step-by-step explanation:
To find the equivalent expression of a fraction, we can either multiply numerator and denominator by same variable or same number, or we can divide both numerator and denominator by same number or same variable .
So if we multiply both numerator and denominator by 2, we will get

Answer:
48 x 3 units
Step-by-step explanation:
6 x 8 is 48
48 x height
Height is 3 units
The solution is:
.1*50+x=.25(50+x) 5+x= 12.5+ .25x
x-.25x=12.5-5 .75x=7.5 x=7.5 or .75
