Answer:
40 degrees
Step-by-step explanation:
Angle ACO = 80 ( 180 - 100)
Angle CAO = 60 (180 - 120)
Angle AOC = 40 (180 - 80 - 60) (TOTAL DEGREES OF A TRIANGLE IS 180)
8+(-10) is like 10-8 except backwards so how i do some problems is like that and then add a negative sign; so say if i were doing 8+(-10), i would do 10-8 which equals 2 and then since 10 is bigger than 8 and it’s a negative number, i would put -2 as my answer
Neither are correct.
Navene has broken the problem up and simply added numbers together to get "4577"
Annabelle is also wrong because whereas she multiplied, she also broke up the numbers in the equation to get "46710"
The answer should be 18,690,300
(4-6i)(6-8i)
24-32i-36i+48i²
24 + -68i - 48
-24-68i
