CAN SOMEONE PLEASE HELP ME WITH MY MATH CLASS PLEASEEE

117 degrees

Step-by-step explanation:

Alternate interior angles in an isosceles trapezoids are supplementary.

We know this is an isosceles trapezoid because the 2 base angles are congruent.

Supplementary means that the two angles add up to 180.

Hence, we can set up an equation.

x+63=180

Subtract 63 from both sides.

x=117

Hi there! :)

x = 117°.

Step-by-step explanation:

Recall that a trapezoid is a quadrilateral, and all interior angles sum up to 360°.

We are given the measure of two angles (at the base) as 63°. We can set up an equation to solve for x:

360° = 63° + 63° + x° + x°

Combine like terms:

360° = 126° + 2x°

Subtract 126° from both sides:

234° = 2x°

Divide both sides by 2:

x = 117°.

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

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.
