You can't do 140 divided by 18
or it will end up like this <span>7.77777777778</span>
Answer:
x= 65 z= 38 y= 77
Step-by-step explanation:
x=65° (opposite angles are equal)
z= 180°-[71+71 (bc the other side is also equal to 71)]
z= 180°-142°=38°
y= 180 - [sum of angle x (65°) and angle z (38°)]
y= 180 - 103= 77°
to make sure ur answer is correct the sum of angle x, y and z MUST = 180
lets check:
65° + 38° + 77° = 180°

Answer:
a x^2/2 is a polynomial because the power of x is 2 which is a positive whole number but 2/x^2 is not a polynomial because the power of x is -2 which is negative whole number.
b.in
![\sqrt{2 x}](https://tex.z-dn.net/?f=%20%5Csqrt%7B2%20x%7D%20)
the power if x will be
![x {}^{ \frac{1}{2} }](https://tex.z-dn.net/?f=x%20%20%20%7B%7D%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20)
which is not a whole number so it is not a polynomial.
but in
![\sqrt{2} x](https://tex.z-dn.net/?f=%20%5Csqrt%7B2%7D%20x)
the power if x is a positive whole number.so it is a polynomial.
c.the greatest power of variable of the term is called degree of polynomial
Circumference= 2πr
Circumference= perimeter
14.28km= 2(3.14)r
14.28= 6.2831853072r
divide both sides by 6.2831853072
2.27= r
ANSWER: The radius is 2.27km
Hope this helps! :)
