Step-by-step explanation:

5x+52=9x+20

subtract 5x on both sides

subtract 20 on both sides

32=4x

divide by 4 on both sides

x=8

plug in x to the equations for A, D, and C

A and D are 92°

C is 56°

B and C will add up to 90, so

90-56=34°

13y-6=34

add 6 on both sides

13y=40

divide by 13

y=40/13 (I don't wanna calculate that)

Step-by-step explanation:

distance walked by him = 1/ 3 miles

time taken in doing so = 3/ 4 hrs.

$speed \: acquired \: by \: him \: = \frac{distance}{time}$

$= \frac{ \frac{1}{3} }{ \frac{3}{4} } \\ = \frac{ 1}{3} \times \frac{4}{3} \\ = \frac{4}{9} \: miles \: hr^{ - 1}$
