Answer:
x = a + b
Step-by-step explanation:
This is a proof
Exterior angle of a triangle = Sum of Interior and opposite angles
Exterior angle of a triangle = x
Sum of Interior and opposite angles = a + b
know that
a + b + c = 180 ______1 (total sum of angles in a triangle)
x + c = 180 _______2 (total sum of angles on a straight line)
from equation 1
c = 180 - (a + b)
from equation 2
c = 180 - x
hence
180 - (a + b) = 180 - x
180 - 180 + x = a + b
6500 lb
The load limit of the bridge is ...
(5000 kg)(2.2 lb/kg) = 11,000 lb
The total of truck and trailer cannot exceed this value, so the trailer's weight cannot exceed ...
11,000 lb -4,500 lb = 6,500 lb . . . max trailer weight
what do you need help with?
Given
Subtract the expression
X is 6 or -6
In absolute value it makes everything positive
