Answer:
79.7
Step-by-step explanation:
average = 20x75=1440
wrong average68+86=154
correct average 1440+154/20=79.7
hope this is correct.
the value of x is
115°+y=180 (being linear pair)
y =180°-115°
therefore, the value of y is 65°.
now again x=y=65°(being corresponding angle)
so, the value of x is 65°.
hope u understood..
C 84.2-79.2/SQRoot(10.2^2/50 + of of 6.8^2/30)
40 is the LCM,
Hope it helps ❤️
