D 100% corect took my test $$$$$$$$$$$$$$
Answer:
A semicircle measures 180°
Half of 180º is 90º
A right angle measures 90º.
Step-by-step explanation:
We need to simplify the expression:

Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:
Now,

On simplifying the above expression we get:




So the simplified form of the expression
.
Answer:
Step-by-step explanation:
thats the link for the diagram
The slope of the line is 2/3, so the angle is arctan(2/3) ≈ 33.69°.
