An angle measures 47°. What are the measures of the angle’s complement and supplement? (1 point)
True [87]
Answer: The angle's complement is 43°.
               The angle's supplement is 133°.


Remember: complementary angles add up to 90°.
                     supplementary angles add up to 180°.

To find the measure of the angle's complement:
47 + x = 90
x = 43

To find the measure of the angle's supplement:
47 + x = 180
x = 133

Find all the square roots of x2 ≡ 53 (mod 77)
Nikolay [14]

Answer:

x=\pm\sqrt{77n+53}

Step-by-step explanation:

We have been given an equivalence equation x^2\equiv 53\text{ (mod } 77). We are asked to find all the square root of the given equivalence equation.

Upon converting our given equivalence equation into an equation, we will get:

x^2-53=77n

Add 53 on both sides:

x^2-53+53=77n+53

x^2=77n+53

Take square root of both sides:

x=\pm\sqrt{77n+53}

Therefore, the square root for our given equation would be x=\pm\sqrt{77n+53}.
