The 3 inside angles of a triangle need to equal 180 degrees.
Since you are given 2 angles, subtract both of those from 180 to find X.
X = 180 - 70 - 30 = 80 degrees.
X = 80
Step-by-step explanation:
since it is in the same line as DE, both have the same slope.
the slope is the ratio of "y coordinate change / x coordinate change" when going from one point on the line to another.
and so by using the coordinates of D and E
x changes by +4 (from 8 to 12).
y changes by -8 (from 32 to 24).
the slope is therefore
-8/+4 = -2

Answer:
A
Step-by-step explanation:
JK is longer than JL and isn't 9 units long
Answer:
a= -3, b= 4 and c= -5
ab + c = (-3)4+(-5) = -12 -5 = -17
