Two sides of a triangle have lengths 10 and 18. Which inequalities describe the values that possible lengths for the third side?

tiny-mole [99]

Well I don't know where inequalities would come in but the third length would be solved as follows.
a^2+b^2=c^2
10^2+18^2=424
$\sqrt{424}$

Answer; $2 \sqrt{106}$
I hope this is correct, its what I would do if I had this equation.

A right triangle has side lengths 7, 24, and 25 as shown below.

Hoochie [10]

Answer: Tan B = 0.2917 (16.26 degrees)

Sin B = 0.2800 (16.26 degrees)

Cos B = 0.9600 (16.26 degrees)

Step-by-step explanation: Please refer to the picture attached for details.

The right angled triangle LNB has been drawn with the sides labeled as 7, 24 and 25 as indicated. With angle B as the reference angle, we can now identify each side as follows;

Side 7 (opposite, facing the reference angle)

Side 24 (adjacent, between the reference angle and the right angle)

Side 25 (hypotenuse, facing the right angle).

Hence, using the trigonometric ratios,

Tan B = opposite/adjacent

Tan B = 7/24

Tan B = 0.2917 (16.26 degrees)

Sin B = opposite/hypotenuse

Sin B = 7/25

Sin B = 0.2800 (16.26 degrees)

Cos B = adjacent/hypotenuse

Cos B = 24/25

Cos B = 0.9600 (16.26 degrees)

If 9 is subtracted from two thirds of a number, the result is 7. Find the number

SSSSS [86.1K]

Answer: 24

Step-by-step explanation:

x/2*3-9=7. So you want to know what x is. So lets start reverse thinking. 7+9=16, 16=x/2*3. That means 16 is 2/3 of x. 16/2=8, 8*3=24! The answer is 24.

Factor the expression. x^2 – x – 42

IgorC [24]

X^2 - x - 42 = x^2 - 6x + 7x - 42 = x( x - 6) + 7(x - 6) = (x-6)(x+7);
The correct answer is a.
