Answer:
80°
Step-by-step explanation:
Three angles are equal
Let the equal angle be x
3x+120=360
3x=240
x=240/3
=80
Hence the three angles are 80∘
Answer:
There are 7 sides.
Step-by-step explanation:
Let's Use the formula that states that the sum of the angles of an n-sided polygon is given by.
S=(n−2)180
Since we are given that the two angles are right, the angles and each of the remaining angles is 144.
And Therefore, the sum is:
S=90
(n−2)144
(n−2)180
=90
+90
+(n−2)144
⇒(n−2)180
−(n−2)144
=180
⇒(n−2)(180
−144
)=180
⇒(n−2)(36
=180
⇒n−2=
36
180
⇒n−2=5
⇒n=5+2=7
Hence, the polygon has 7 sides.
Answer:
x=0
Step-by-step explanation:
x-5=11-13
x-5=-2
+5 on both sides
x=0
Answer:
Charlotte spend 
of day trying on jeans
Step-by-step explanation:
Charlotte spent part of day on shopping = 
She spent part of shopping time on trying jeans =
We are supposed to find What fraction of the day did Charlotte spend trying on jeans.
She spent fraction of the day in trying jeans = 
She spent fraction of the day in trying jeans =
Hence Charlotte spend of day trying on jeans
