Marsha runs 1/2 of the distance that her brother runs each day. She also runs 1/2 mile to warm up each day. If, on one day, her brother runs 6 miles, what distance does Marsha run that day?

i got 10.28 but that rounds up to 10.3

step-by-step explanation:

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
