-1 and 16/25
Negative one and sixteen twenty-fifths
Answer:
x<5
Step-by-step explanation:
-8+x<-3
x<-3+8
x<5
On the number line, you express this as the non-filled circle arrow (the filled circle one is for greater or less than AND equal to or these signs, ≤ ≥) and put it on 5 with the arrow pointing all the way down the left, as x is any number less than 5. There is an attachment of what it should look like, if it helps further.
Answer:
C
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
114° is an external angle of the triangle , thus
y + y = 114°
2y = 114° ( divide both sides by 2 )
y = 57° → C
45 degrees.
To find the central angle or angle of rotation divide 360 (degrees in a circle) by the number of sides (octogon=8) 360/8=45
Answer:
12 sides
Step-by-step explanation:
Given that :
Two of the exterior angles are = 60
The rest are each 24 ;
Find n, the number of sides of the polygon
The sum of the exterior angles of a polygon = 360
2 of the angles are 60° each ;
360 - (2 * 60)
360 - 120 = 240°
The remaining sides are 24° each ;
Hence, number of sides that are 24°
240° / 24° = 10 sides
Hence, total number of sides :
10 sides (14° each) + 2 sides (60° each)
10 + 2 = 12 sides
