Answer:
a = 54
Step-by-step explanation:
In geometry, the angles in a triangle add up to 180.
The unmarked angle at the top of the triangle = 180 - (a+10+44)
Or you could say that same angle = 180 - 2a because it is supplementary to the exterior angle... so
2a = a + 10 + 44
2a-a = 54
a = 54

Answer:
a(4) = -17
Step-by-step explanation:
hello :
use : a(n) =a(n-1) -5
a(n) -a(n-1) = -5 (common differnce for arithmetic sequence)
the ni-eme term is : a(n) = a(1) +(n-1)d d = -5 and a(1) = -2
so : a(n) = -2 +(n-1)(-5)
a(n) = -5n+3
when : n= 4 a(4) = -5(4)+3 =-17

Hey there! I'm happy to help!
We want to find to find the length of the wire that will go around the friends field. The distance around something is called the perimeter. To find this, we will take our two sides with the length of 219 and two sides with the width of 7525 and then add them.
2(219)+2(7525)=15488
Therefore, we will need a wire with a length of 15488.
I hope that this helps! Have a wonderful day!
