Answer:
x=1/2, y=0
Step-by-step explanation:
-2x+y=-1
1-4x+y=-1
-4x+y=-2
-2x=-1, x=1/2
-2(1/2)+y=-1, y=0
I’m sure your answer is D. 180 - 125 will get you 55.!
Have a nice day!
Answer:
Proved: AC = BD
Step-by-step explanation:
The complete question related to this with diagram can be found at toppr website.
Given: O is the mid point of AB and CD
Find attached the diagram
∠COA = ∠BOD (vertical angles are equal)
∠AOD = ∠COB (vertical angles are equal)
For ∆AOC
AC + OC + OA = 180° (sum of angles in a triangle)
For ∆DOB
DB + OB + OD = 180° (sum of angles in a triangle)
OC = OD (sides are equal)
OA = OB (sides are equal)
Since both ∆AOC and ∆DOB are equal to 180°, AC = DB.
DB = BD
Proved: AC = BD
The answer is(might not be right but i think A)
