Answer: Option A. Line segment A
Step-by-step explanation: we know that
The height of the triangle must be perpendicular to the base of the triangle
so
In this problem
The segment A is perpendicular to the given height
therefore
The base is the line segment A
Answer:

• Group the h terms by organised term arrangement :

• Then using distributive property, factorise out the value h so that the reverse is true.

• for the variable "lw", divide it by h in order to add it to the bracket of (w + l). Make sure the reverse is true:

• finally, completely factorise out the value h

Answer:
12
Step-by-step explanation: it is 12 because LCM is least common mulitiple. The LCM is the smallest number of all the number that can DIVIDE EVENLY. 6 cannot divide evenly.
Answer:
The slope of a line perpendicular to the line whose equation is 4x - 5y = 10 is -5/4.
Step-by-step explanation:
provided the equation;
4x- 5y=10.(let it be equation of line1 )
and the other line be line2
from perpendicularty principle
M1×M2= -1
BUT for M1(slope of line L1)
y= mx+c
where "c" is constant value.
"m" is slope.
therefore
5y= 4x - 10
(dividing by five throughout)
y=(4x/5) - 2
y= (4/5)x - 2
therefore M1= (4/5)
Returning back to our principle
M1×M2= -1
(4/5)M2=-1
<u>M2= -5/4</u>
