Alex is making an isosceles triangle-shaped pennant to support her school’s athletic team on sports day as shown below. Side ac is the same length as side an . Alex rotates the pennant 90 degrees clockwise to stick it to the wooden pole

  104°

Step-by-step explanation:

The marked angles have the same measure, so ...

  (4x +10) = (7x -11)

  21 = 3x . . . . . . . . . . . add 11-4x

  7 = x . . . . . . . . . . . . . divide by 3

Then angle C is ...

  C = (4x +10)° = (4(7) +10)° = 38°

The measure of angle A is 180° -2(38°) = 104°.

_____

That angle will have the same measure whether the pennant is rotated or not.

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
