(A)
Step-by-step explanation:
Given the trend line which goes through (2, 79) and (12, 24).

The equation which can be simplified to find the slope of the trend line in the scatterplot is 
The correct option is A.
Answer:
m2=125°
m3=65°
m4=125°
m5=65°
m6=125°
m7=65°
m8=125°
i know the reason in French if you want
Step-by-step explanation:
m2=180-65=125°
m2 = m4 =125°
m3 =m1 =65°
m3= m5 =65°
m4 =m6=125°
m7=m5 =65°
m8=m6=125°
Answer:
The correct option is option A
Step-by-step explanation:
Given two triangles in which ∠B=∠E=50° and AB=DE=10 units.
we have to find the missing condition need to show the two triangles ABC and DEF congruent by AAS.
The condition given are
∠B=∠E
AB=DE
One side and one angle congruent given we need one more angle of both the triangles congruent such that the side does not lies between the two angles.
Hence, the possible angles are ∠C and ∠F.
The correct option is option A
