Answer:
the LCM for 5 and 6 is 30
the LCM for 4 and 8 is 8
Answer
7. 30
8. 54
Step-by-step explanation:
For 7 do 2x+3x=90 because it is a right angle
then solve for x and get 15
to get the angle you are looking for multiply 2 by 15
and get the answer 30
For 8 to find the value of x you would need to...
add (4x+6) + (11x-6)= 180 because 180 is a straight angle.
Then simply solve for x and get 15x=180 which equals 12
The to get the angle you plug it in to (4x+6) and get the answer 54
I believe the answer is D.
In this case, because both numbers are negative, -5.31 is greater then -5.313 as it is closer to the positive numbers on a number line. I hope that helped! :D
