If m<3=54 find each measure

Step-by-step explanation:

Given m∠3 = 54°

a). m∠1 + m∠2 + m∠3 = 180° [Linear angles]

   m∠1 + 90° + 54° = 180°

   m∠1 = 180° - 144°

           = 36°

b). m∠2 = 90° [Given]

c). m∠4 = m∠1 [Vertically opposite angles]

    m∠4 = 36°

d). m∠2 = m∠5 = 90° [Vertically opposite angles]

e). m∠3 = m∠6 = 54° [Vertically opposite angles]

f). m∠7 = m∠1 + m∠2 [Corresponding angles]

           = 36° + 90°

           = 126°

g). m∠8 = 180° - m∠7 [Linear pair of angles]

             = 180° - 126°

             = 54°

h). m∠9 = m∠7 = 126° [[Vertically opposite angles]

i). m∠10 = m∠8 = 54° [Vertically opposite angles]

j). m∠11 = m∠1 = 36° [Corresponding  angles]

k). m∠12 = m∠3 + m∠2 = 54° + 90° [Corresponding angles]

                                      = 145°

l). m∠13 = m∠11 = 36° [Vertically opposite angles]

m). m∠14 = m∠5 + m∠6

               = 90° + 54°

               = 145°

the answer is 375 miles
