Answer:
This is the case ASA, with 2 triangles are congruent (ABD and CBE)
ABD = CBE because
Angle BAD = Angle BCE (as pic)
AD = CE (as pic)
Angle ADB = Angle CEB
Step-by-step explanation:
Angle ADB = Angle CEB because
ADB = 180 - BAD - B
CEB = 180 - BCE - B
BAD = BCE (as pic)
X^2 - y^2 - 2x + 6y - 8
<span>= (x^2 - 2x + 1) - (y^2 - 6y + 9) - 8 - 1 + 9 </span>
<span>= (x - 1)^2 - (y - 3)^2 </span>
<span>= [(x - 1) - (y - 3) ] [(x - 1) + (y - 3)] </span>
<span>= (x - 1 - y + 3) ( x - 1 + y - 3) </span>
<span>= (x - y + 2) (x + y - 4)</span>
Answer:
100
Step-by-step explanation:
Hello There!
∠4 and ∠8 are corresponding angles
corresponding angles are congruent so if ∠4 = 100 then ∠8 also equals 100
