To solve the top triangle, use the sine of 45° and find the shared side length (y):
sin(45°) = y / 12
12(sin(45°) = y
y = 8.485
(The side y is opposite of the bottom triangle's 30° angle.)
Use the tangent of 30° to find the side length of x.
tan(30°) = 8.485 / x
x(tan(30°)) = 8.485
x = 8.485 / (tan(30°))
x = 14.696
The side length of x is approximately 14.696 units.

Answer: Bigger
Step-by-step explanation: If you put -1/4 in decimal form you get -.25. If these numbers were positive, 1.4 would obviously be bigger than .25, but since these numbers are negative, -.25 would be bigger than -1.4.
Answer:
-1
Step-by-step explanation:
The midline is the middle point
Subtract the midline from the maximum
5-2 = 3
Then we need to subtract this number from the midline to get to the minimum
2-3 = -1
The minimum is at -1
