The measure of one of two complementary angles is 6 degrees less than one half the measure of the other. Find the measure of the
solmaris [256]
It's helpful to choose letters to represent the measures of these complementary angles.  Let x represent one and y the other.

What does "complementary angle" mean?  x + y = ??

Let x be the smaller angle.  First, we take "half the measure of the larger angle," or (y/2).  Then we subtract 6 degrees from this result (y/2).  The result is the xmaller angle, x.

Now you have two equations in x and y.  Solve for one of these angles, and then find the other.  Please show your work.

Given P(A)=0.4P(A)=0.4, P(B)=0.26P(B)=0.26 and P(A\text{ or }B)=0.436P(A or B)=0.436, find the value of P(A\text{ and }B)P(A and
Stolb23 [73]

If the probabilities of A, B, and A or B are 0.4, 0.26, and 0.436. Then the probability of A and B will be 0.224.

<h3>What is the addition rule of size for two subsets?</h3>

For two subsets A and B of the universal set U, we have:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Then the expression can be written as

P(A ∩ B) = P(A) + P(B) - P(A ∪ B)

The probabilities are given below.

P(A) = 0.4

P(B)=0.26

P(A ∪ B) = 0.436

Then the probability of A and B will be

P(A ∩ B) = P(A) + P(B) - P(A ∪ B)

P(A ∩ B) = 0.4 + 0.26 - 0.436

P(A ∩ B) = 0.66 - 0.436

P(A ∩ B) = 0.224

Write the converse of the following statement. Then determine its validity.
madam [21]

The converse and the validity of the statement is:

  • If a parallelogram is a rectangle, then the diagonals are congruent.
  • TRUE.

The statement is given as:

If the diagonals of a parallelogram are congruent, then is the parallelogram is a rectangle

Considering the following statement

If a then b

Its converse is:

If b then a

So, the converse of the given statement is:

If a parallelogram is a rectangle, then the diagonals are congruent.

The diagonals of a rectangle are true.

Hence, the validity is true.

So, the true statement is (b)
