Answer:
( 3 - 7i) • ( 2 - 5i) = ( - 29 - 29i)
Step-by-step explanation:
The formula is :
(a+bi) • (x+yi) = ax+by•i^2+(ay+bx)i
and since i^2 = -1 it can be written as :
ax - by + (ay + bx) i
( 3 - 7i) • ( 2 - 5i) =
( - 29 - 29i)

Answer:
1. You can prove that a line parallel to one side of a triangle divides the other 2 sides proportionally by using the Triangle Proportionality Theorem.
2. You prove the base angles are congruent by constructing the angle bisector through the vertex angle of an isosceles triangle. By constructing the angle bisector, we designed two congruent triangles and then used CPCTC to show that the base angles are congruent.
