The angle just above 40 degrees angle = 1/2 * 70 = 35  making the 'double' angle at top = 35 + 40 = 75.  The 'double' angle opposite = 180 - 75 = 105 ( because  opposite angles of a cyclic quadrilateral add up to 180 degrees). Also the top angle of this one = 40 degrees ( because  2 equal sides  both subtend same angle).

So the bottom angle = 105-40 = 65 degrees.

Now x = this angle ( alternate segment theorem )

Therefore x = 65 degrees.

In the isosceles trapezoid, m∠S=68∘ .<br><br> What is m∠Q ?
zmey [24]

9514 1404 393

Answer:

  112°

Step-by-step explanation:

Same-side angles of a trapezoid are supplementary.

  m∠P = 180° - m∠S = 180° -68° = 112°

The angles of an isosceles trapezoid match their symmetrical counterparts.

  m∠Q = m∠P

  m∠Q = 112°

I don't understand rational and irrational numbers
PSYCHO15rus [73]

A rational number is a number which can be expressed as a fraction whose numerator and denominator are both integers and whose denominator is not equal to zero. Rational numbers include all integers, fractions, mixed numbers, and some decimal numbers.

 

Note : All terminating and repeating decimal numbers are rational numbers because those numbers can be expressed as a fraction. On the other hand, a non repeating number and non terminating decimal, like square root of 2, is an irrational number.
