A triangle has sides with lengths of 60 centimeters, 63 centimeters, and 87 centimeters. Is it a right triangle
lozanna [386]
We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:
60^2+63^2 = 87^2
7569 = 7569

This is, indeed correct, thus, this <em>is </em><em>a right triangle.</em>

Find the length of side x in simplest radical form with a rational denominator<br><br>​
HACTEHA [7]

Answer:

x =  \sqrt{2}

Step-by-step explanation:

\tan 30 \degree =  \frac{x}{ \sqrt{6} }  \\  \\  \frac{1}{ \sqrt{3} } =  \frac{x}{ \sqrt{6} }    \\  \\ x =  \frac{ \sqrt{6} }{ \sqrt{3} }  \\  \\ x = \frac{ \:  \sqrt{3}  \times  \sqrt{2} }{ \sqrt{3} }  \\  \\ x =  \sqrt{2}

What is the value of x?
NISA [10]
Since vertical angles are congruent, (4x+7)=5(x-4). So simplifying we get 4x+7=5x-20. If we add 20 on both sides we get 4x+27=5x. Now when we subtract x from both sides, we get x=27

If f(x)=-3x-5 and g(x)=4x-2,find (f-g)(x)
ira [324]

f(x) = -3x - 5, g(x) = 4x - 2

(f - g)(x) = f(x) - g(x) = (-3x - 5) - (4x - 2) = -3x - 5 - 4x + 2 = (-3x - 4x) + (-5 + 2)

(f - g)(x) = -7x - 3
