Answer:
An acute angle is greater than 0 and less than 90
Step-by-step explanation:
An acute angle is greater than 0 and less than 90
A right angle is 90 degrees
An obtuse angle is greater than 90 and less than 180
On the left we have a 30-60-90 triangle. Find the length of side JL:
Since sin 30 deg = |JL| / ( 8sqrt(2) ), |JL| = 8 sqrt(2)*(1/2) = 4 sqrt(2).
Now, on the right, we have a 45-45-90 triangle with hypotenuse 4 sqrt(2).
Since c^2 = a^2 + b^2 (Pyth. Theorem), 16(2) = x^2 + x^2, or 32 = 2x^2, or 16 = x^2. Thus, x = 4 (answer)
