One more than the degree.
Answer: 6.
Answer:
Im pretty sure its the first one. If angle BAC is congruent to angle ABC then angle BAC = 58 degrees

Solution:
1)
Statement Reason
x ║t Given
m∠16=m∠7 Given
m∠16=m∠1 Corresponding angles
m∠7=m∠1 Substitution
k║w Alternate exterior angles equal
(Property of parallel lines)
2)Part A:
Sum of angles in any triangle is 180 degrees.
m∠BAC+m∠ABC+m∠BCA= 180
Substituting the values :
4x+10+12x-6+3x+5=180
Adding like terms :
19x+9=180
19x=171
x=9.
Part B:
Substituting x value :
m∠BAC=4x+10=4(9)+10=46
m∠ABC=12x-6=12(9)-6=102
m∠BCA=3x+5=3(9)+5=32.
Part C:
m∠1=180-46=134
m∠2=180-102=78.
m∠3=180-32=148.
Part D:
Angle BAC and angle FAC are angle made on straight line and are linear .Such angles are called linear pairs.
Part E:
Angle BCE and Angle DCA are vertically opposite angles.

The answer is 13/18. find the common denominator which is 54 now put 54 on both sides, also multiply the old denominator with the opposite nominator, like so 5*6=30 and 9*1=9, so the new fraction would be 9/54 + 30/54 =39/54 simplified by 3 is 39/3 =13 and 54/3 =18, so you get 13/18.
