Answer: x>2
Step-by-step explanation:

Answer:
1.
by using Pythagoras theorem
h²=p²+b²
h²=12²+40²
h=√1744
AB=42
2.
x+48°+90°=180°{sum of interior angle of triangle}
x=180°-138°
x=42°
Answer:

Step-by-step explanation:
These are the terms of a geometric sequence with n th term formula
= a 
where a is the first term and r the common ratio
r =
=
= - 
the first term a = 64, hence
= 64

Answer:
y = -3x
Step-by-step explanation:
The slope formula gives the slope of the segment between the given points.
m = (y2 -y1)/(x2 -x1)
m = (-3 -(-5))/(2 -(-4)) = 2/6 = 1/3
The slope of the perpendicular line is the opposite reciprocal of this, so is ...
m' = -1/(1/3) = -3
A perpendicular line is ...
y = -3x
