Answer:
∠L = 54°
Step-by-step explanation:
5x + 2x + 3x = 180 (all angles in a triangle add up to 180)
10x = 180
x = 18°
∠L = 3x
sub x = 18
3(18) = 54
∠L = 54°
C because if you add them all together
The answer is false, Max Plank's hypothesis was not disproved by Albert Einstein's discovery of quanta.
X²>49
well, I don't know a formula but this is how I would solve it
I first solve x²=49 to obtain x=+/-7
so then would it be x>+/-7?
if we try 8 it works
if we try -9 it works
so answer is x>+/-7
basically x<-7 or x>7
