Answer:
Step-by-step explanation:
Let's take a look at the given angle 135°
The sketch of the angle which corresponds to
unit circle and can be seen in the attached image below;
The trigonometric ratios are as follows for an angle θ on the unit circle:
Trigonometric ratio related ratio on coordinate axes
sin θ 
cos θ 
tan θ 
csc θ 
sec θ 
cot θ 
From the sketch of the image attached below;
The six trigonometric ratio for 135° can be expressed as follows:











C=25x+.10
C is the total cost. To get the total cost you add the consistent fee of $25 per day, times the number of days. You add $.10 for every mile driven.
The result of division is 21.392
Rounded to the nearest tenth its 21.4 answer
(because the hundredth digit is 9 so you add 1 to the tenth digit.)
Answer:
Substitution Property
Step-by-step explanation:
So we know that:

And we also know that:

And by using a specific property, we get that:

Essentially, we <em>substituted</em> B for A.
So, this is an example of the substitution property, where if two sides/angles are congruent, we can substitute them for each other.
