△ABC is a right triangle. m∠A = 32° m∠B=90°; AC = 9 and AB=5. Choose the expression used to find BC?
Westkost [7]

Answer:

Step-by-step explanation:

The diagram of the right angle triangle is shown in the attached photo.

From the given right angle triangle,

AC represents the hypotenuse of the right angle triangle.

With m∠32 as the reference angle,

BC represents the adjacent side of the right angle triangle.

AB represents the opposite side of the right angle triangle.

To determine BC, we would apply

the Sine trigonometric ratio which is expressed as

Sin θ= opposite side/hypotenuse. Therefore, the expression used to find BC is

Sin 32 = BC/9

BC = 9Sin32

1. If there is a decrease of 31 percent, what decimal do we multiply by to get the amount after the decrease?
sdas [7]

answer

1.

Short answer: 0.69Take 100. 31% = 31, 100-31=69Of course, when you increase the result by 31 percent you do not get the 100 back. But that was not the question.But, for completeness what do I multiply by to get the number, when adding 31 percent, gives me the original number, it is 0.7633 (1/1.31)

2.

Your measure start at 16. So that is the basis (unless stated otherwise) upon which you reference the change.

That is:

16

20−16

is you fraction.

This gives:

16

4

→

16÷4

4÷4

=

4

1

For this to be a percentage we need the denominator such that it becomes 100. Thus we have:

4

1

→(

4

1

×1)→(

)=

To express this in the standard script form we have 25%
