Answer:

b = 133 and c = 47

Step-by-step explanation:

c has the same degree as the opposite side

to find the angle of b

1. supplementary line is 180 degrees

2. subtract 180 - 47

3. answer is 133

Brandon buys a radio for 48.43 dollars in a state where the sales tax is 7% ​
Elza [17]

Answer:

Given : Brandon buys a radio for $43.99 .sales tax  rate is 7%.sales tax is a consumption tax imposed by the government on the sale of goods and services.

Let the price of Radio before the sales tax be $x. Sales tax on $x is 7% x.

Price before sales tax + Amount of sales tax= Cost of Radio.

x+7%x =43.99

Or x+0.07x=43.99

1.07x=43.99

Dividing both sides by 1.07.

x= 41.11

Cost of Radio before tax = $41.11

Sales tax paid = 43.99-41.11= 2.88

Tax paid = $2.90 (To the nearest cent)

Plsssssss help<br>got 20 mins​<br>the question is: The sin of angle DCB is
Elena L [17]

Answer:

i. <DCB = 53.13^{o}

ii. Sin of <DCB = 0.8

Step-by-step explanation:

Let <DCB be represented by θ, so that;

Sin θ = \frac{opposite}{hypotenuse}

Thus from the given diagram, we have;

Sin θ = \frac{4}{5}

        = 0.8

This implies that,

θ = Sin^{-1} 0.8

   = 53.1301

θ = 53.13^{o}

Therefore, <DCB = 53.13^{o}.

So that,

Sin of <DCB = Sin 53.13^{o}

                    = 0.8

Sin of <DCB = 0.8

suppose someone tells you that she has a triangle with sides having lengths 2.6,8.1 and 8.6. Is this a right triangle? why or wh
sveta [45]
If you're only provided with the lengths of a triangle, and you're asked to determine whether or not the triangle is right or not, you'll need to rely on the Pythagorean Theorem to help you out. In case you're rusty on it, the Pythagorean Theorem defines a relationship between the <em>legs</em> of a right triangle and its <em>hypotenuse</em>, the side opposite its right angle. That relationship is a² + b² = c², where a and b are the legs of the triangle, and c is its hypotenuse. To see if our triangle fits that requirement, we'll have to substitute its lengths into the equation.

How do we determine which length is the hypotenuse, though? Knowledge that the hypotenuse is always the longest length of a right triangle helps here, as we can clearly observe that 8.6 is the longest we've been given for this problem. The order we pick the legs in doesn't matter, since addition is commutative, and we'll get the same result regardless of the order we're adding a and b.

So, substituting our values in, we have:

(2.6)² + (8.1)² = (8.6)²

Performing the necessary calculations, we have:

6.76 + 65.61 = 73.96
72.37 ≠ 73.96

Failing this, we know that our triangle cannot be right, but we <em>do </em>know that 72.37 < 73.96, which tells us something about what kind of triangle it is. Imagine taking a regular right triangle and stretching its hypotenuse, keeping the legs a and b the same length. This has the fact of <em>increasing the angle between a and b</em>. Since the angle was already 90°, and it's only increased since then, we know that the triangle has to be <em>obtuse</em>, which is to say: yes, there's an angle in it larger than 90°.

Find the quotient of 95 and 3.25
Lelu [443]
To find the quotient of 95 and 3.25 we may do something like this:

95 ÷ 3.25 =
= 95 ÷ 3 1/4 =
= 95 ÷ 13/4 =
= 95 * 4/13 =
= 380/13 =
= 29 3/13

I hope it'll help you :)
