Answer:
Length of DB = 19 (Approx)
Step-by-step explanation:
Given:
AC=7
AD=6
BC=18
Find:
Length of DB
Computation:
AB = AD + DB
AB = 6 + DB
AC + BC ≥ AB
7 + 18 ≥ 6 + DB
19 ≥ DB
Length of DB = 19 (Approx)
What is the first equation?
Remember perpendicular lines have reciprocal slopes.
So if we have 1/2 we flip to fraction and sign becoming -2.
You then input the point to find the y-intercept.
4. 1/3 6.-0.9 or -9/10 8. 2 1/3 10. -3.45 12.4.54 or 4 27/50
