Find the value of x in each case:
Margaret [11]

Answer:

x = 11°

4x = 44°

Step-by-step explanation:

Line BC || Line EF... (given)

BF is transversal.

\angle BFG + \angle BFE = 180\degree\\.. (straight \: line \: \angle 's) \\ + \angle BFE = 180\degree\\\angle BFE = 180\degree-147\degree \\\angle BFE = 33\degree\\

\angle BED is exterior angle of \angle EBF

Hence, by remote interior angle theorem of triangle, we have:

m\angle BED = m\angle EBF + \angle BFE  \\4x = x + 33\degree \\4x - x = 33\degree \\3x = 33\degree \\x = \frac{33}{3}\\\huge \purple {\boxed {x = 11\degree}} \\4x = 4\times 11\degree \\\huge \orange{\boxed {4x = 44\degree}}

Consider a collection of envelopes consisting of 2 red envelopes​, 2 blue envelopes​, 2 green envelopes​, and 3 yellow envelopes
77julia77 [94]

The probability that all three randomly selected envelopes are yellow without replacement is 1/84.

<h3>What is a combination?</h3>

It is an arrangement of a set of numbers from a total set where the order of the set is not relevant.

We have,

2 red envelopes​

2 blue envelopes​

2 green envelopes​

3 yellow envelopes.

Total number of envelopes = 9

The probability that all three randomly selected envelopes are yellow without replacement.

= \frac{^3C_1}{^9C_1} \frac{^2C_1}{^8C_1} \frac{^1C_1}{^7C_1}

= (3/9) x (2/8) x (1/7)

= (3x2x1)/(9x8x7)

= 1/84

Thus,

The probability that all three randomly selected envelopes are yellow without replacement is 1/84.
