a=2
Answer:
(m1) slope of DE=(7-1)/(10-a)=6/(10-a)
(m2) slope of EF=(11-7)/(7-10)=4/-3=-4/3
since line are perpendicular
m1m2=-1
6/(10-a) ×-4/3=-1
6/(10-a)=3/4
6×4=3(10-a)
24=30-3a
3a=30-24
a=6/3=2

Answer:
x=65
Step-by-step explanation:
Step 1: Add -3 to both sides.
√x−1+3+−3=11+−3
√x−1=8
Step 2: Solve Square Root.
√x−1=8
x−1=82(Square both sides)
x−1=64
x−1+1=64+1(Add 1 to both sides)
x=65
Check answers. (Plug them in to make sure they work.)
x=65(Works in original equation)
