The second one !!!
I’m pretty sure
C is the least that is beause it is .015 which is smaller than 0.15
<1 and <2 are complementary : given
<1+<2=90 : definition of complementary
<1 congruent <3 : given
<2 congruent <4 : given
<3 congruent <4 : transitive property
D = 390mi
r = 60 mi/h
390/60 = 6.5
(t) = 6.5 h
