This is what i got:
C) (g - 7)^6
Answer:
EF is 4 units.
Step-by-step explanation:
It is given that the two triangles
are congruent to each other i.e.

Coordinates are given as:
A(-1,1)
B(2,4)
C(3,1)
As per the property of congruence, all the corresponding sides and angles of the two triangles are equal to each other.
i.e. AB = ED
BC = DF
AC = EF
We are given with the coordinates of points A, B and C here from which we can easily calculate the side AC using the distance formula.

Where
are the coordinates of the two points whose distance is to be calculated.
So,

Hence, <em>AC = EF = 4 units</em>
Answer: b

Answer:
180
Step-by-step explanation:
From basic rules of a triangle we know that the interior angles of a triangle have to add up to equal 180°
But here is a formula for future references for finding the sum of the interior angles
interior angle sum = (n-2)180
where n = number of sides
and here is an example:
a triangle has 3 sides so we plug in 3 for n
(3-2)180
3-2=1
1*180 = 180
so the interior angles add up to equal 180
Answer: c
