Answer:
its A
Step-by-step explanation:
First we know that,
3x+15=5x-65 because of vertical angle thr.
y=y because of reflex property
there are 360 degrees in a circle so..
3x+15+5x-65+2y=360
3x+15=5x-65
x=40
so each 2 of the angles are...(40*3+15)=135
Then your new equation is
135+135+2y=360
2y=90
<u>y=45</u>
Hope this helps :)
8-9n=15 I believe
At least I hope
Answer:
<u>x = 49</u>
Step-by-step explanation:
Since the line is parallel, the value of 2x - 8 is equal to 90.
=> 2x - 8 = 90
=> 2x = 98
=> <u>x = 49</u>
Answer: 706.5
Step-by-step explanation:
A= pi r squared
A= 3.14x15 squared
15 squared = 225
A= 3.14x225
