Using the Pythagorean Theorem, we have x^2+(x+2)^2=51^2, and
x^2+ x^2+4x+4=2x^2+4x+4=51^2. After that, we subtract 51^2 from both sides to get 2x^2+4x-2597. Using the quadratic formula (x=(-b+-sqrt(b^2-4ac))/2a in ax^2+bx+c), we get around 35 for x. We did + instead of minus after b due to that it can't be negative! x+2=37, so you save 35+37-51=around 21 feet
Answer:
C) 3/4
Step-by-step explanation:
It is three steps out of four.
Answer:
118
Step-by-step explanation:
the length ED is equal to EC
so
the angle is also the same
that's mean the angle ECD is equal to 31
then to find the another angle just do like this
=180–31–31
=118
