Answer:
<h2><u>x = 21</u></h2>
Explanation:
x = 
= <u>21</u> degree will be the answer.
{The sum of angle of opposite circumscribed quadrilateral in circle is 180°}
X-2y=1
subtract x
-2y = 1-x
divide by -2
y = x-1

Answer:
16.67
Step-by-step explanation:
Each side is about 4.167 yards so the perimeter is roughly 16.67 yards
$0.03+$0.04=$0.15x4=$0.60
A]
D=R×t
d=5.8r
d2=5.1(r+7)
0.7r=35.7
r=51 mi/hr
thus the average speed on the outbound trip would be:
51+7=58 mi/hr
b]
let speed of fishing boat=x km/h
speed of cruise ship=(x+12.5) km/h
distance traveled by fishing boat=11.5×x=11.5x km
distance traveled by cruise ship=(x+12.5)×11=(11x+137.5) km
Total distance covered by the ships:
11.5x+11x+137.5=322
22.5x=322-137.5
22.5x=184.5
thus
x=184.5/22.5
x=8.2 km/h
The speed of fishing boat is 8.2 km/hr
