(ab + 4a - 6) - (ab - 6) = ab + 4a - 6 - ab + 6 = (ab - ab) + (6 - 6) + 4a = 4a
Answer:
50 degrees
Step-by-step explanation:
in a kite the diagonals are perpendicular and the smallest one divide it in two isosceles triangles. This mean that if the see at the top one we have that the two angles of its base are both 40 degree
a triangle has the sum of interior angles that is 180 degrees
180 - 80 = 100 degrees
the height of a isosceles triangle is also its bisector
a bisector divides an angle in two congruent angles, so we have
1: 100/2 = 50 degrees
Answer:
X=8
Step-by-step explanation:
........... ....................... . . ........
The gene flow would increment or quality stream would increment between the two parts, and speciation would not happen. The probability of speciation would diminish as qualities were shared between the two gatherings.
