Answer:
3240°
Step-by-step explanation:
For a regular icosagon,
sum of interior angles measure=180(n-2)°
180(20-2)
180(18)=3240°
Answer: x=5 or x=−13
Step-by-step explanation:
8x−65=−x2
8x−65−(−x2)=−x2−(−x2)
x2+8x−65=0
(x−5)(x+13)=0
x−5=0 or x+13=0
x=5 or x=−13
Answer:
y=2x+20
Step-by-step explanation:
x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20

See the attached figure
we know that
MN=16 in-------------> PQ=MN
PQ=16 in
<span>L is the midpoint of PQ-----------> distance QL=</span><span>PQ/2
QL=8 in
if </span>m∠QLM = 45°
then
MQ=QL
MQ=8 in
Perimeter=[MN]*2+[MQ]*2=16*2+8*2=48 in
the answer is 48 in
