You have to begin by using the triangle sum therom. That means Angle DEC would be 64°, Angle D would be 76°, and angle C would be 40°
Step-by-step explanation:
I think you will get x this way:
x=180°-140°
x=40°
Answer is C weak negavite
weak, because as the value became smaller that 1 the correlation weakens. negavite because it is a negative value (-0.23)
-2/3-(-1 1/3) =
-2/3 + 1 1/3 =
4/3 - 2/3 =
<em>2/3</em>
12 - (-5) =
12 + 5 =
<em>17</em>
-1 - (-6) =
-1 + 6 =
6 - 1 =
<em>5</em>
-3 3/8 - 7/8 =
27/8 - 7/8 =
20/8 =
2 4/8 =
<em>2</em><em> </em><em>1/2</em>
It is an acute triangle since all the sides are less than 90 degrees (it's also equilateral)
