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:











Divide the numerator and denominator by 5
This should give you 1/3

Answer:
a = 10/3
Step-by-step explanation:
This can be written as:

Anything to the power of 1/3 means to find the cube root. We can simplify this to:
I just multiplied 4 and 1/3 (because of the second index law
). Now, we can add the powers because the bases are the same and we are multiplying (first index law):

a = 10/3
