Answer:
121°
Step-by-step explanation:
sum of angle in a Pentagon =540
so: 135+92+105+87+x=540
419 + x= 540
x= 540-419
x=121°
Answer:
The simplified form is: or
Step-by-step explanation:
So we need to find the simplified form of:
We know that:
(a^m)/(a^n) = a^(m-n)
Then:
Simplifien the expression:
So, the simplified form is:
or
Answer:
2 or 4
Step-by-step explanation:
Step-by-step explanation:
L= W+5
P= 9W
P= 2L+ 2W
9W= 2(W+5) + 2W
9W= 2W +10 +2W
9W = 4W +10
5W = 10
W = 2
L=7
P= 9(2)
P= 18
A= LW
A= 7 x 2
A= 14
