x = 117
Step-by-step explanation:
The sum of the interior angles of a pentagon is 180°(5 -2) = 540°. This means ...
x +59 +138 +140 +86 = 540
x +423 = 540 . . . simplify
x = 117 . . . . . . . . subtract 117

Step-by-step explanation:
85.4/5
=<span>17.08 in a minute
</span>then 17.08/60=<span>0.28 yars per second
so 0.28*70=</span><span>19.9 yards in 70 seconds
</span><span>=18.2 meters
or
85.4 yards = </span>78 meters 5 mins
so 5*60=300 seconds
78/300
=<span>0.26 meters per second
in 70 seconds, he/she will swim 70*0.26
=</span><span>18.2meters</span>
Answer:
Option C
Step-by-step explanation:
Sum of two angle in complement = 90

a + 5x + 13 = 90
a = 90 - (5x + 13)
a = 90 - 5x - 13
a = 77 - 5x
