Answer: 1/3

There are C(4,2) = 6 ways to choose a pair of numbers. Only 2 of those pairs are supplementary measures {22, 158} and {62, 118}. The probability is 2/6 = 1/3.

The triangles ABD, ADC and ABC are similar (AA stands for "angle, angle" and means that the triangles have two of their angles equal).

If two triangles have two of their angles equal, the triangles are similar.

Therefore the sides of triangles are in proportion.

$\dfrac{c}{6}=\dfrac{2}{c}$

cross multiply

$c\cdot c=6\cdot2\\\\c^2=12\to c=\sqrt{12}$

Use the Pythagorean theorem for calculate x:

$x^2=2^2+(\sqrt{12})^2\\\\x^2=4+12\\\\x^2=16\to x=\sqrt{16}\to\boxed{x=4}$

Use properties to evaluate 2/3 • (- 3/4 / 1/8) 1/3 A.-4 B. 4 C.-4/3 D.4/3

Bond [772]

Answer:

Step-by-step explanation:

First you do the division in parentheses and you get (-3/4*8/1) = -24/4 = -6

The new exercise becomes 2/3 *(-6)*1/3

Next, since there are only multiplication we have to do then in order from left to right so we have

-12/3*1/3 = -12/9

We can simplify by 3 and we get -4/3
