Answer:
65°
Step-by-step explanation:
Sum of interior angles of a triangle = 180°
⇒ m∠EAB = 180 - 90 - 70 = 20°
⇒ m∠DAG = 90 - 45 - 20 = 25°
⇒ m∠AGD = 180 - 90 - 25 = 65°
ΔADG ≅ ΔAFG
⇒ m∠AGD = m∠AGF = 65°
ΔABE ≅ ΔAFE
⇒ m∠AEB = m∠AEF = 70°
-7 degrees fahrenheit is warmer

Step-by-step explanation:
Number of sample 
Number of correct response 
Calculating the Sample proportion:
Formula:


Well
one possible thing is if
a=1992
and if b or c or d =0
examples
a=1992
b=0
c=0
d=0
another is if a=b=c=1
and d=1989
there are many possibilities
