Astronomers measure large distances in light-years. one light-year is the distance that light can travel in one year, or approximately 5.88 x 1012 miles. suppose a star is 1.23 x 102 light-years from earth. in scientific notation, approximately how many miles is it?

12.3 x 10^12
7.23 x 10^13
7.23 x 10^14
5.88 x 10^12

Parallelogram rstu is a rhombus. m∠r = 120° what is m∠t = 120 (what is m∠rsu? )

Myra took a picture of the sky one afternoon when two jet airplanes appeared to draw a pair of parallel lines with their vapor trails. the vapor trails from two other jets flying from another direction crossed over the parallel trails. she printed her picture and labeled the angles and lines. assume lines c and d are parallel and 2 measures 98°. which statements are true? check all that apply. 3 = 6 = 98° 3 = 14 = 98° 4 = 8 = 82° 4 = 12 = 82° 5 = 8 = 82°
