if interior angle is 170, subtract 170 from 180 to find exterior angle:
180-170 = 10 = exterior angle
the sum of exterior angles is 360 so divide by exterior angle to find sides:
360 /10 = 36 sides
Answer:

Step-by-step explanation:
Answer:
620
Step-by-step explanation:
100% must be the the answer so 700% must be 7 times that number.
4340÷7=620
Answer:
None.
Step-by-step explanation:
1 - 4 + 121
= -3 + 121
= 118
121 + 1 - 41
= 122 - 41
= 81
141 - 121
= 20
1 - 21 - 1 - 41
= -20 - 1 - 41
= -21 - 41
= -62
None of the expressions have a value of -2.
Answer:
and 
Step-by-step explanation:
(a)
A = 
× 4
× 
= 2 ×
= 
× 
← rationalise the denominator
= units²
(b)
Using Pythagoras' identity in the right triangle
let hypotenuse be h , then
h² = (4 )² + ( )²
= 32 + 
= 
+
= 
( take the square root of both sides )
h = 
= 
× ← rationalise the denominator
h =
