What value of y makes the 2 triangles congruent by SSS? (Side Side Side)

aivan3 [116]

Answer:

y = 8

Step-by-step explanation:

for the triangles to be congruent, 2y + 20 must equal 36.

2y + 20 = 36

subtract 20 from each side of the equation:

2y = 16

divide both sides by 2:

y = 8

The question is this: Rationalize the denominator and simplify.

Neko [114]

9514 1404 393

Answer:

$\dfrac{20+5\sqrt{3}}{13}$

Step-by-step explanation:

Multiply numerator and denominator by the "conjugate" of the denominator.

$\dfrac{5}{4-\sqrt{3}}=\dfrac{5(4+\sqrt{3})}{(4-\sqrt{3})(4+\sqrt{3})}=\dfrac{20+5\sqrt{3}}{4^2-(\sqrt{3})^2}=\boxed{\dfrac{20+5\sqrt{3}}{13}}$

This is done in different scenarios in order to take advantage of the factoring of the difference of squares. Square root terms and imaginary terms in the denominator can be eliminated in this way.

A standard deck of playing cards contains 52 cards, equally divided among four suits (hearts, diamonds, clubs, and spades). Each

The order does not matter, so we will be using combinations here. 52C1 is the first one since there is only one possibility. 16C1 is the second. You have to multiply these two, so 52 X 16 = 832.
