Answer:

  • ∠ROK = 36°
  • ∠CKO = 96°
  • ∠C = 60°

Step-by-step explanation:

The same-side angles at each base are supplementary, so ...

  ∠ROC = 180° -120° = 60°

Because the trapezoid is isosceles, 60° also the measure of ∠C.

The angle sum theorem tells you ...

  ∠COK +∠ROK = ∠ROC

  24° + ∠ROK = 60°

  ∠ROK = 36° . . . . . . subtract 24°

__

The sum of angles in ΔCKO is 180°, so ...

  ∠C +∠COK +∠CKO = 180°

  60° +24° +∠CKO = 180°

  ∠CKO = 96° . . . . . . . . . . . . . subtract 84°

Factor the polynomial.
mixer [17]

Answer:

Final answer is choice B. (5x-2y)^2

Step-by-step explanation:

We need to factor the given expression 25x^2-20xy+4y^2

25x^2-20xy+4y^2

=25x^2-10xy-10xy+4y^2

=5x(5x-2y)-2y(5x-2y)

=(5x-2y)(5x-2y)

=(5x-2y)^2

Hence final answer is choice B. (5x-2y)^2
