Answer:
Solution given:
the angles 2xº and 4yºare complementary
so
2x+4y=90°
dividing both side by 2we get
x+2y=45°
<u>the value of x + 2y</u><u> </u><u>i</u><u>s</u><u> </u><u>4</u><u>5</u><u>°</u><u>.</u>
Answer: There are 7,677 streets named as " First Street" and 7, 189 streets named as "Main Street" .

D is 900.
E is 1080.
I'm tired too, I have been doing math for 3 hours now.
The area is 28.26
to find the radius you have to divide the diameter by 2 which you’ll get 3
then plug it into the equation
A=3.14•3^2
