Answer:
2. angle BAD is equal to angle DCB?
3. angle CBA is equal to angle ADC, then
4.triangle BEA is equal to triangle DEC and triangle BEC is equal to DEA
Step-by-step explanation:
since line BCD is equal to line DAB
AND line CBA is equal to line ADC
and because BEA triangle equals DEC, angles BEA and DEC are congruent
and angle BEC is equal to DEA
and yeah your right, it would be supplementary.
Answer:
Look for a pair of factors of
24
whose difference is
5 . 24
= 8 × 3 and 5 = 8 − 3 So x 2 + 5 x − 24 = x 2 + ( 8 − 3
) x −
(
8
×
3
) = (
x + 8
) (
x − 3
)
So the solutions of x 2 + 5
x −
24
=
0 are x = −
8 and x = 3
