Answer:
n<1
Step-by-step explanation:
4n−5<−1
Add 5 to both sides.
4n−5+5<−1+5
4n<4
Divide both sides by 4.
4n/4<4/4
n<1
Answer:
2.598cm
Step-by-step explanation:
Area of a triangle =1/2 * base * Height
Given
ARea = 39.6cm^2
Base= 12in = 2.54 * 12
Base = 30.48cm
Required
Height
Substitute
39.6 = 1/2 * 30.48 * H
39.6 = 15.24 * H
H = 39.6/15.24
H = 2.598cm
Hence the height of the triangle is 2.598cm
Answer:
=
= 
Step-by-step explanation:
The set of ratios must have numerators coming from the same triangle and denominators coming from the same triangle. The other set of ratios have some numerators coming from both triangles and/or denominators coming from both triangles.
The answer is 2(3tan(x)-tan^3(x))/(1-3tan^2(x)) but it is a very long and tedious calculation using alot of trig identities.
