<span>In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
The short leg is </span>the side opposite the 30 degree angle. If the short leg =x, then the hypotenuse = 2x
The ratio of the short leg to the hypotenuse in the given triangle is cos(60°)

Answer is C. 1:2
15% of 40
Of = Multiplication
15% Multiply by 40
Set up a equation
15/100= x/140
Cross Multiply
15* 140= 100*x
2100= 100x
Divide both sides by 100x
2100/100x= 100x/100x
X= 21
Answer:
-26.0454545455
Step-by-step explanation:
Answer:
s = (14 + 7 + 11)/2 = 32/2 =16
=> area = sqrt(16*(16-14)*(16-11)*(16-7)) = ~37.95
=> h = 2*Area/Base = 2*37.95/14 = 5.42
For all just put them together in x and y. For example, f(2)=-2 would be (2,-2). f(1)= 1 would be (1,1).
