Answer:75

Step-by-step explanation:

180-64 gives you the angle not labelled which is 116 then to work out size of angle formula is 180(n-2) n being sides so 180(6-2) = 720 so 720 minus all the angles = 75 I think lol

Answer:

x = 75

Step-by-step explanation:

180-64 = 116

Since this is a hexagon (6 vertices), the angles all add up to 720

116 + 121 + 155 + x + 90 + 163 = 720

x + 645 = 720

x = 75

Lf x+1/x=12 then find the value of x3+1/x3​
Tresset [83]
Answer:

Explanation:

First we find what x is:
x + 1/x = 12
x + 1 = 12x
1 = 12x - x
1 = 11x
1/11 = x
Or x = 1/11

Plug x value in x^3 + 1/x^3

(1/11)^3 + 1/(1/11)^3
= (1^3/11^3)+ 1/(1^3/11^3)
= (1/1331 + 1)/1/1331
= (1/1331 + 1331/1331)/1/1331
= 1332/1331 x 1331/1
= 1332/1
= 1332

Therefore, x^3 + 1/x^3 = 1332
