We are going to make the product step by step.
 We have:
 (6 + 5i) * (3-7i)
 Multiplying:
 ((6) * (3)) + ((6) * (- 7i)) + ((5i) * (3)) + ((5i) * (- 7i))
 Rewriting:
 18 - 42i + 15i - 35i ^ 2
 18 - 42i + 15i - 35 * (- 1)
 18 - 42i + 15i + 35
 53 - 27i
 Answer:
 
the product of and (6 + 5i) and (3-7i) is:
 
53-27i

trasher [3.6K]

Answer:

Isosceles Triangle; Acute Triangle

Step-by-step explanation:

Review your definitions of the different types of triangles:

acute triangle- a triangle that has three acute (less than 90 degrees) angles

obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.

right triangle- a triangle that had one right (90 degrees) angles

isosceles triangle- a triangle with two congruent sides and one unique side and angle.

equilateral triangle-  a triangle with three congruent sides and three congruent angles.

scalene triangle- a triangle with no congruent sides and no congruent angles.

With these definitions, we can classify ΔPQR as an isosceles acute triangle.
