The figure is a right triangle so we can use the Pythagorean theorem to find the third side AKA the hypotenuse.

Pythagorean theorem = a² + b² = c² where A and B are the legs of the triangle and C is the hypotenuse.

39² + 80² = c²

169 + 6400 = c²

6569 = c²

Square root both sides to cancel out the squared variable.

√6569 = √(c²)

√6569 = c

The third side, the hypotenuse, is √6569 units long.

I NEED HELPPPP<br> 2( 2.5 - | -6|) need the answer ASAPPPPP
Sloan [31]

The equivalent value of the expression is -7

<h3>Modulus of a function</h3>

The modulus of an expression of value is equal to the positive of such function or value.

Given the expression

2(2.5 - |-6|)

Since the value of -6 is a modulus, the expression will become;

2(2.5 - |-6|) = 2(2.5) - 2(6)

2(2.5 - |-6|) = 5 - 12

2(2.5 - |-6|) = -7

Hence the equivalent value of the expression is -7

Solve 60 = 10√ y – 3 . A. y = –39 B. y = –10, 39 C. y = 39, –39 D. y = 39
bearhunter [10]

Answer:

y = 39

Step-by-step explanation:

The equation is:

60=10\sqrt{y-3}

You clear the square root and have:

6=\sqrt{y-3}

To clear the square root you just square 6 and get

36=y - 3

And you clear Y to get

y=36 + 3

y=39
