Answer:
R3: Definition of Linear Pair
S4: m<3 + m<4 = 180°
R5: Substitution Property of Equality
Answer:
The Original Number is 36
Step-by-step explanation:
Given:
y is the number in units place
x is the number in tens place
Original Number = 
is equation 1
Now after interchanging the digits
New number = 
New Number = 27 + Original Number
Substituting Valus in above equation we get.

let this be equation 2
Adding equation 1 and 2 we get

Substituting value of y in equation 1 we get

x=3 and y=6
Original Number =
Answer:x=3
Step-by-step explanation:
the 3 angles of a triangle equal 180
you add 105 and 46, which equals 151
you subtract 151 from 180 to see what the missing angle is (29)
you would make 6x+11 equal to 29
-subtract 11 from 29= 18
6x/6, 18/6
the answer is 3
hope this helps! :)
