In the figure, AngleRQS Is-congruent-to AngleQLK. 3 lines are shown. Lines S P and K N are parallel. Line R M intersects line S
stepan [7]

Answer:

x=108

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠RQS≅m∠QLK -----> by corresponding angles

m∠KLM+m∠QLK=180° -----> by supplementary angles (consecutive interior angles)

we have that

m∠RQS=x° ----> given problem

so

m∠QLX=x°

m∠KLM=(x-36)° ----> given problem

substitute

(x-36)\°+x\°=180\°\\2x=180+36\\2x=216\\x=108

Lin read for x minutes, and Elena read for more than that. Write an expression for the number of minutes Elena read. Only use de
Vikentia [17]
<h2>Explanation:</h2><h2 />

In this exercise, we know some facts:

  • Lin read for x minutes.
  • Elena read for more than that.

The problem tells us nothing about the number of minutes Elena read more than Lin. However, let's say Elena read one-third more than the number of minutes Lin read. Therefore:

<u>For Lin:</u>

Number \ of \ minutes \ Lin \ read=x

<u>For Elena:</u>

Number \ of \ minutes \ Elena \ read=x+\frac{1}{3}x \\ \\ Number \ of \ minutes \ Elena \ read=\frac{3x+x}{3} \\ \\ Number \ of \ minutes \ Elena \ read=\frac{4x}{3} \\ \\ Number \ of \ minutes \ Elena \ read=\frac{4x}{3} \\ \\ \\ By \ using \ decimals: \\ \\ Number \ of \ minutes \ Elena \ read \approx 1.33x

Kyle said that it is not possible to draw a trapezoid that is a rectangle. Trisha said it is possible. Who is correct? Support y
neonofarm [45]

Answer:

Kyle is correct, because it is not possible to draw  a trapezoid that is a rectangle.

Step-by-step explanation:

Trapezoid:

  • It is a quadrilateral with only one pair of of parallel sides
  • Also in Trapezoid all the four angles are not right angle
  • In Trapezoid is it not necessary that the diagonals bisect at all the cases
  • The opposite angles are supplementary

Rectangle:

  • Opposite sides of a rectangle are parallel and equal, thus having two pairs of parallel lines
  • In a Rectangles all the four angles are 90 degrees  i.e, right angle
  • Diagonals of rectangles must bisect each other
  • The sum of any two angles is supplementary
