If I did my math right x=9. All 3 degrees need to equal 180 in total so 65+40=105

9*9=81

105+81=186

186-6=180. If I am wrong I am sorry btu I’m am 99% sure this is correct

Answer:


Step-by-step explanation:

well there are 180 degrees in a triangle so 180 - (65+40) = 75

75 - 6 = 69

69/9 = 7.67
