What method can be used to prove the triangles below are congruent

Mathematics

Answer:

<h2>SSS?</h2>

Step-by-step explanation:

I don't know why the answers don't offer this an option. However, the side that shares both triangles must be congruent to itself and the other highlighted congruent parts are sides, not angles. Therefore by my calculations, the answer has to be SSS, but this isn't a choice.

50% of Number is 250 what is 80% of that number
Yakvenalex [24]
We have an equation: 250/?= 50/100

Cross multiply:
50*?= 250*100
⇒ ?= 250*100/50= 500

The number is 500~

We have another equation: ?/500= 80/100

Cross multiply:
100*?= 80*500
⇒?= 80*500/100= 400

80% of 500 is 400~

If sin(32)=x , then sin(4) cos(4) cos(8) cos(16)=..............
svp [43]

If sin 32 is equal to x, then sin 4 · cos 4 · cos 8 · cos 16 is equal to x/8 by using <em>double angle trigonometric</em> functions.

<h3>How to simplify an expression by trigonometric expressions</h3>

<em>Trigonometric</em> expressions are formulas that utilize <em>trigonometric</em> functions. <em>Trigonometric</em> functions are a kind of <em>trascendental</em> functions, that is, functions that cannot be described in <em>algebraic</em> terms.

In this question we must simplify a given expression by using the following trigonometric formula:

<em>sin 2x = 2 · cos x · cos x</em>   (1)

Now we proceed to expand the expression given:

x = sin 32

x = 2 · sin 16 · cos 16

x = 4 · sin 8 · cos 8 · cos 16

x = 8 · sin 4 · cos 4 · cos 8 · cos 16

Thus,

sin 4 · cos 4 · cos 8 · cos 16 = x/8

If sin 32 is equal to x, then sin 4 · cos 4 · cos 8 · cos 16 is equal to x/8 by using <em>double angle trigonometric</em> functions. \blacksquare

calls arrive at lynn ann fish's hotel switchboard at a rate of 2.0 per minute. the average time to handle each is 10 seconds. th
BartSMP [9]

The probability that the operator is busy is 33.33% if the call rate is 2 per minute and average time to handle is 10 seconds.

Given rate of calls 2 per minute and average time to handle a call is 10 seconds.

We have to find the probability that the operator is busy.

Probability is the chance of happening an event among all the events possible. The value of probability lies between 0 and 1.

Probability= number of items/ total items

If rate is 2 per minute then the customers handled in 1 hour=2*60=120

The average time to handle a call=10 seconds.

Therefore customers to be handled in 1 hour=360 (10*6*60)

Probability that the operator is busy is as under:

Probability=λ/μ

=120/360

=1/3

=1/3*100

=33.33%

Hence the probability that the operator is busy is 33.33%.
