MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

3 ⋅ 12 − 12 = 36 - 12 = 24

3 ⋅ [26 − 2 ⋅ (3 + 6)] = 3 · (26 - 2 · 9) = 3 · (26 - 18) = 3 · 8 = 24

Using the permutation formula, it is found that the people can be chosen for the roles in 6840 ways.

The order in which the people are chosen is important, as there are different roles, hence the <em>permutation formula</em> is used.

<h3>What is the permutation formula?</h3>

The number of possible permutations of <u>x elements from a set of n elements</u> is given by:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this problem, 3 people will be chosen from a set of 20 people, hence the number of ways is given by:

$P_{20,3} = \frac{20!}{17!} = 6840$

14. In a right triangle, if one acute angle has measure 10x + 6 and the other has measure 2x + 7, find the larger of these two a

lubasha [3.4K]

Answer:

421/6 degrees

Step-by-step explanation:

The acute angles of a right triangle are complementary, so

$10x+6+2x+7=90 \\ \\ 12x+13=90 \\ \\ 12x=77 \\ \\ x=\frac{77}{12}$

So, the acute angles measures 421/6 degrees and 119/6 degrees, and thus the larger angle is 421/6 degrees.
