50 + 31sz
31sz = -50
sz = -50/32
hope this helps
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 : impossible
Answer:
Step-by-step explanation:
Start
<F = <Q Given
<GPF = <RPQ Vertically opposite angles
<FGP = <QRP A triangle has 180 degrees. 2 equal angles means the third pair must be equal
Triangle GPF ~ Triangle RPQ AAA
end
I don't see any way to make these triangles similar except by stating the statement and why it is so. There really are no yes / no choices. If you get another answer, choose it.

JL/LE = 90/27 Given
KL /LD = 90/27 Given
<JLK = <DLK Vertically opposite
Are the ratios equal Yes Then is the angle included Yes
Then the triangles are similar.
Are the ratios not equal No then the triangles cannot be similar
Is the angle not included Then similarity cannot be proved.
ΔJLK ≈ ΔDLK Equal Ratios and included angle === similarity
