Answer:
A, B, C
Step-by-step explanation:
You are given one side congruent to its corresponding side, so eliminating postulates that require 2 sides: HL, SAS.
You are given all three angles congruent and one side (the hypotenuse), so any of these can be used:
AAS, HA, ASA
Let the length be x
width = x - 8
Perimeter = Length + Length + Width + Width
x + x + x - 8 + x - 8 > 184
4x - 16 > 184
4x > 184 + 16
4x > 200
x > 50
Therefore:
Length > 50
Width > 50 - 8
Width > 42
Ans: Length > 50, Width > 42
It should be 12 because 60/5 =12
Answer:
1. L1 = 
2. O2 = 
Step-by-step explanation:
Given: x = 
1. To make L1 the subject of formula;
x = 
cross multiply to have;
L2 - L1 = xL1(O2 - O1)
collect like terms,
L2 = xL1(O2 - O1) + L1
factorize the right hand side;
L2 = L1[x(O2 - O1)]
L1 = 
2. To make O2 the subject of formula;
x = 
cross multiply to have;
L2 - L1 = xL1(O2 - O1)
open the bracket to have;
L2 - L1 = xL1O2 - xL1O1
⇒ xL1O2 = L2 - L1 + xL1O1
O2 = 
=
