There are 360 degrees in the rhombus which means the equilateral triangles has 180 degrees (because it is half the rhombus and also it is the angle sum of a triangle). It is equilateral meaning all sides and angles are the same so they all must be 60 (180/3)
Now this must mean that angle a is equal to the opposing angle being 60

Simplify. 5i−√54 Enter your answer, in simplest radical form, in the box.
Sliva [168]

Answer:

5i - 3 \sqrt{6}

Step-by-step explanation:

The given expresion is

5i -  \sqrt{54}

We need to remove the highest perfect square from the radicand.

We rewrite 54 as 6*9

This gives us:

5i -  \sqrt{9 \times 6}

This is the same as

5i -  \sqrt{9}  \times  \sqrt{6}

We now simplify to get:

5i - 3 \sqrt{6}

Interest centers around the life of an electronic component. Let A be the event that the component fails a particular test and B
nekit [7.7K]

Answer: a. 0.61

b. 0.37

c. 0.63

Step-by-step explanation:

From the question,

P(A) = 0.39 and P(B) = 0.24

P(success) + P( failure) = 1

A) What is the probability that the component does not fail the​ test?

Since A is the event that the component fails a particular test, the probability that the component does not fail the​ test will be P(success). This will be:

= 1 - P(A)

= 1 - 0.39

= 0.61

B) What is the probability that a component works perfectly well (i.e., neither displays strain nor fails the test)?

This will be the probability that the component does not fail the​ test minus the event that the component displays strain but does not actually fail. This will be:

= [1 - P(A)] - P(B)

= 0.61 - 0.24

= 0.37

C) What is the probability that the component either fails or shows strain in the test?

This will simply be:

= 1 - P(probability that a component works perfectly well)

= 1 - 0.37

= 0.63
