Answer:
The answer is C use a calculator
Step-by-step explanation:
not that hard lol
Like in real life problems?
if yes then when conducting a survey, when grading quizzes/assignments, etc
90° is equal to 
or 1.5707 radians.
Step-by-step explanation:
Step 1:
If an angle is represented in degrees, it will be of the form x°.
If an angle is represented in radians, it will be of the form 
radians.
To convert degrees to radians, we multiply the degree measure by 
.
For the conversion of degrees to radians,
the degrees in radians = (given value in degrees)().
Step 2:
To convert
90°,
radians.
So 90° is equal to or 1.5707 radians.
To find the equation of a line knowing two points it passes through, we must first find the slope and then substitute the x and y values to figure out the y intercept.
First thing is to find the slope using the formula m = Δy ÷ Δx
m = 5 - (-2) ÷ 4 - (-5)
Now we simplify
m = 7 ÷ 9
Our equation so far is y = 7/9x + b. Now we can substitute the values of x and y from a point to figure out the answer. The equation here uses the point (4,5)
5 = 7/9 · 4 + b
Get b on one side
5 - 28/9 = b
Simplify
b = 1 + 8/9
That makes the equation of the line y = 7/9x + (1 + 8/9)
