The shaded figure below is a diagram of a triangular tabletop. A triangle has a base of 192 centimeters and a height of 113 centimeters.

Which two measures can be used as the base and height when finding the area of the tabletop?
113 cm and 140 cm
113 cm and 192 cm
159 cm and 140 cm
159 cm and 192 cm

113.42

i hope that is right.

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
