well how do i find any of those variables? to use in that formula?

Answer 4

@nitz

Answer 5

is the answer 220

Answer 6

yes or no??????

Answer 7

PQR=360-2x=360-2(70)=360-140=220

Answer 8

sorry the upper formula was for length not measure
so the correct formula for measure of arc is
360-2(angle)

Answer 9

also in a quadrilateral ,,,,,,,,sum of interior angles is 360

Answer 10

ok so its 220?

Answer 11

ya

Answer 12

wouldnt it be like 140 though because it doesnt seem like that would be even 180

Answer 13

no you need to subtract it from 360

Answer 14

oh ok. so it would be 140.

360-140=220
