Answer:
160°
Step-by-step explanation:
Minor Arc NR is equal to the measure of its central angle, S.
S and 20 are supplementary angles, so they add up to 180.
So, s +20 =180
S = 160, so NR = 160 as well
Answer:
Angle 8 = 84 degrees
Angle 5 = 96 degrees
Step-by-step explanation:
Angle 8 = 84 degrees because Angle 2 and Angle 8 are inside opposite which makes them equivalent.
Angle 5 = 96 degrees because 180-84=96

Represent the boots print with y and the Liz's feet with x
<em>To calculate how much the boot is longer than her feet, we simply get the difference between the length of the boot's print and her feet;</em>
i.e.
<em>Note that her boot print (y) will always be greater than her feet (x)</em>
<em></em>
Take for instance;
The difference will be
Answer:
7x^2 + 29xy -2y^2 + 8y
Step-by-step explanation:
3x(x+5y)+2y(7x-y)+4(x^2+2y)
Break all the brackets and you would hot:
= 3x*x + 3x*5y + 2y*7x - 2y*y + 4*x^2 + 4*2y
= 3x^2 + 15xy + 14xy -2y^2 + 4x^2 + 8y
= 3x^2 + 4x^2 +15xy + 14xy - 2y^2 + 8y
= 7x^2 + 29xy -2y^2 + 8y
Hope this help you :3
Hi
two lines are parallel only if they have the same slope.
So : 3x+4y = 12
4y = 12 -3x
y = 12/4 - 3x/4
y = 3 - 3/4 X
y = -3/4 X +3
Slope is -3/4
and 6x+2y = 6
2y = 6 -6x
y = 6/2 - 6x/2
y = 3 - 3X
y = -3X +3
Slope is = -3
As -3/4 ≠ -3 then the two lines are not parallel.
