X=-19°F-7°F
x=-26°F
-19°F because -24 rose up 5 before the sun set, making it -19.
Number 5 is 135 because angle 3 is congruent to 7 and 7 is 135
(-27-19=-2x) then you add then you get (-46=-2x) divide by -2 you get 23
so x=23
The answer is 14.33333 but you will have to round which you will just have 14.3
To find the number of non-defective chips, we simply use this equation:
2,000 * 4/5
8000/5
Now you simply divide:
1600
1600 chips aren't defective
