(-24)+9=-15
(-15)-9=-24
n=-15
Answer: 5
Step-by-step explanation:
a^2 + b^2 = c^2
12^2 + x^2 = 13^2
144 + x^2 = 169
x^2 = 25
square root both sides
x = 5
to check, do 12^2 + 5^2 =169
sqrt of 169 is 13

Answer:
the retail price is $47.30
Step-by-step explanation:
<u>Given</u>:
The given triangle is a right triangle.
The length of the hypotenuse is 31 units.
The length of the leg is 23 units.
One of the angle is x.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the trigonometric ratio.
Thus, we have;

Substituting
, the side opposite to the angle x measures 23 units and the hypotenuse is 31.
Thus, we have;

Dividing, we get;

Taking
on both sides of the equation, we get;


Rounding off to the nearest whole integer, we get;

Thus, the value of x is 48°
Hence, Option c is the correct answer.
Answer:
a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression (e.g. 3 in 23 = 2 × 2 × 2).
