Answer:

Step-by-step explanation:
The reference angle is an acute angle that angle in standard position makes with the positive x-axis.
The given angle in radians is

This angle is already acute and hence it is itself a reference angle.
The reference angle of any angle in the first quadrant is the same angle.
Answer:
The first is 0.046 and the second is 0.033
Step-by-step explanation:
Answer:
144x^2−y^2−169 because ther are no like terms
Step-by-step explanation:
Hey!
To simplify the equation provided we must first start off by grouping like terms.
<em>Original Equation :</em>
10 + 3c + 5d - 7c + d
<em>New Equation {Grouped Like Terms} :</em>
3c - 7c + 5d + d + 10
Now we add similar elements.
<em>Old Equation :</em>
3c - 7c + 5d + d + 10
<em>New Equation {Added Similar Elements} :</em>
-4c + 5d + d + 10
Next we add the other similtar elements.
<em>Old Equation :</em>
-4c + 5d + d + 10
<em>New Equation {Add Similar Elements} :</em>
-4c + 6d + 10
<em>So, this means that the equation 10 + 3c + 5d - 7c + d simplified is</em> -4c + 6d + 10.
Hope this helps!
