Answer:
x= 60° degree
Step-by-step explanation:
180°-40°= 140°
140= x+ x+ 20
140 -20 =2x
2x = 140 - 20
2x = 120
x = 60°
Answer:
the side = the radius for a hexagon.
so, area = 6 times the area of one equilateral triangle of side 4.
Answer:
Step-by-step explanation:
If the relationship between cost and the number of chairs produced is linear, we would write an equation that expresses this relationship in the slope intercept form. It is expressed as
y = mx + c
Where
m represents the slope
c = intercept.
Slope = (y2 - y1)/(x2 - 1)
y2 = final value of y = 4800
y1 = initial value of y = 2200
x2 = final value of x = 300
x1 = initial value of x = 100
Slope, m = (4800 - 2200)/(300 - 100) = 2600/200 = $13 per chair.
To determine the intercept, we will substitute y = 4800, x = 300 and m = 13 into y = mx + c. It becomes
4800 = 13×300 + c = 3900
c = 4800 - 3900 = 900
The equation becomes
y = 13x + 900
Answer:
EF is not parallel to HL.
Step-by-step explanation:
They are not parallel because angle HLG is not equal to angle EFG. If the two lengths WERE parallel, those two angles would be equal. Angle GHL would be equal to angle GEF, but they are not equal, either.
Hope this helps!
