For this case what you should do is use the following trigonometric relationship:
tan (x) = C.O / C.A
Where
x: angle
C.O: opposite leg
C.A: adjoining catheto
Substituting the values we have:
tan (60) = long / short
tan (60) = long / 2
long = 2 * tan (60)
long = 3.46
Answer:
long = 3.46

Which is the correct algebraic expression after combining like terms? 6 c d + 3 c minus 7 d minus 3 c d + 4 d + one-third c 3 c

IgorC [24]

Answer:

$3cd+3\frac{1}{3}c - 3d$ OR 3cd + 3 and one-thirds c minus 3d

Step-by-step explanation:

Given the algebraic expression:

$6cd+3c-7d-3cd+4d+\frac{1}{3}c$

Combining like terms

$= 6cd-3cd+3c+\frac{c}{3}-7d+4d\\ \\= 3cd + \frac{10c}{3} -3d\\\\= 3cd+3\frac{1}{3}c-3d$

The final expression gives the required answer on combining the like terms.

What is the factorization of 3x2 – 8x + 5?

Tanzania [10]

Answer:

$(x-1)(3x-5)$

Step-by-step explanation:

Factorize means convert and expression into multiple factors.

You have to find to factor that multiplied equals the original equation. Firts of all you split the expression of square X into 3X an X, so you guarantee that when you multiply 3X by X, the result is 3X^2.

After doing that, you need to think in numbers that equals the middle term (8X) and the constant (5).

-1 and -5 guarantee you that the multiplication of them results into +5, so you start with those numbers. Then you have to find where to put them in order to find the -8X.

-5 x X = -5X

-1 x 3X = -3X

And adding those two expresion you find the -8X that you need!

Please try to solve it multiplying term by term and check the final equation.
