Answer: 1. sqrt(19); 2. sqrt (96); 3. sqrt (105); 4. sqrt (28)

Step-by-step explanation: All you have to do is use Pythagoras' Theorem.

So, e.g. in question 1, the equation would be x^2 + 9^2 = 10^2.

x^2 = 100 - 81

x^2 = 19

Therefore, x = sqrt (19) or (19)^1/2

BTW, sqrt means square root.

And now you apply it for everything else.

The longer leg of a 30,-60,-90 degree triangle is 18: what is the length of the other leg

taurus [48]

Answer:

The other legs are 9 and 9√3

Step-by-step explanation:

The longer side of a 30-60-90 degree rectangle is 18.

The other legs will be

$\frac{x}{2}$

and

$\frac{x}{2} \sqrt{3}$

Where x is the longest side, which is given as 18.

Therefore one leg will be:

$\frac{18}{2} = 9$

and the other leg will be:

$\frac{18}{2} \sqrt{3} = 9 \sqrt{3}$

Molly earns a rebate each month on her movie tickets and books. She earns $0.25 for each movie ticket and $2 for each book. Last

Sliva [168]

The algebraic equation is 4(0.25)+2x=17

STEP 1: Simplify both sides of the equation

1+2x=17 or 2x+1

STEP 2: Subtract both sides

2x = 16

STEP 3: Divide both sides by 2

2x/2 = 16/2

x = 8
