Answer:

C. x = 100°

Step-by-step explanation:

The sum of angles in a quadrilateral is 360°. The figures are given as congruent (even though they don't look like it), so corresponding angles have the same measure.

80° +75° +x +105° = 360°

x = 100° . . . . . . subtract 260°

The circumference of a circle is 11pi ft. find its diameter, in feet

mixer [17]

Answer:

The diameter would be 11 feet

Step-by-step explanation:

C = pi * d

we don't know D so we rearrange the equation to solve for D by dividing both sides by pi:

C/pi = d

Now we plug in everything

11pi/pi = d

The pi cancel each other out leaving with 11 feet

Therefore D = 11 feet
