A squared+B squared=C squared
6 squared+B squared=7 squared
36+B squared=49
B squared=49-36=13
B squared=13
b=square root of 13
b=3.61
choice B

A^2 + B^2 = C^2

6^2 + B^2 = 7^2

36 + B^2 = 49

B^2 = 13

B = 3.61

The ratio of the measure of the acute angle in a right triangle is 1/2 . Find the measures of the two angles

AleksandrR [38]

30° and 60°.

<h3>Further explanation</h3>

We will solve the problem of the measures of angles in the triangle.

Recall this condition:

The acute angle ⇒ an angle of less than 90°.
The right angle ⇒ an angle of exactly 90°.
A right triangle ⇒ a triangle in which one angle is a right angle.
The interior angles ⇒ the angles inside a triangle.
All the interior angles in a triangle , i.e., $\boxed{ \ \angle A + \angle B + \angle C = 180^0 \ }$

<u>Given that:</u>

The ratio of the measure of the acute angle in a right triangle is ¹/₂.

<u>Question:</u>

Find the measures of the two angles.

<u>The Process:</u>

We call it the triangle ABC. An interior angle inside is a right angle, e.g., ∠A = 90°.

From the ratio of two other acute angles, i.e., 1: 2, we call it ∠B = x and ∠C = 2x.

Let's arrange the three angles in ABC triangle as follows:

$\boxed{ \ 90^0 + x + 2x = 180^0 \ }$

Both sides subtracted by 90°.

$\boxed{ \ x + 2x = 180^0 - 90^0 \ }$

$\boxed{ \ 3x = 90^0 \ }$

Both sides divided by 3.

We get $\boxed{ \ x = 30^0 \ }$

We substitute the value of x back into B and C.

$\boxed{\boxed{ \ \angle B = x\ } \rightarrow \boxed{ \ \angle B = 30^0 \ }} \\\boxed{\boxed{ \ \angle C = 2x\ } \rightarrow \boxed{ \ \angle C = 60^0 \ }}$

We have succeeded in getting the measures of the two angles.

Debbie owns a clothing store that designs T-shirts and shorts. She sells the T-

balandron [24]

Answer:

$ 208

Step-by-step explanation:

This problem can be solved in a very simple way and the hourly earnings of each product are calculated.

That is, its sale value for the time it costs to create it:

For T-shirts: Each one is worth $ 6 but in one you can make two, therefore

$ 12 per hour.

For shorts: Each one is worth 13 and one is made per hour, therefore

$ 13 per hour

Which means that the most productive thing is to sell all shorts.

It can work 16 hours maximum, therefore it can make 16 shorts.

So:

13 * 16 = $ 208

And this would be the maximum value that can be obtained and complies with the restriction of at least 12 products but less than 24 products.

Mr. Stewart bought a new battery for his car. The battery cost $72. Since batteries are a taxable item, he had to pay a sales ta

Sladkaya [172]

Answer: $77.40

Step-by-step explanation:

First you take the 7.5% and turn it into a decimal and to do that you have to divide 7.5 by 100 which gives you .075. You then multiply 72 by .075 to know how much money you will pay with tax and you get $5.40. then you add $5.40 to $72 to get the total coast of the battery, which is $77.40.

The total cost of the battery was $77.40.
