Answer: 135°
<u>Step-by-step explanation:</u>
First, let's find the sum of the interior angles of an octagon (8-sided polygon).
S = 180(n - 2) where n = 8
S = 180(8 - 2)
S = 180(6)
S = 1080
Next, to find ONE angle, divide the sum by the number of angles in the polygon (octagon has 8 angles)
I = S/n
I = 1080/8
I = 135
Answer:
= a² + b²
= a × a + b × b

HCF of 60 and 80 is 20.
36
Plug in -7 as m and 2 as n into the expression:
4 | m - n |
4 | -7 -2 |
Solve:
4 | -9 |
4(9)
= 36
