Answers

Answer:

a = 1.8 cm

Step-by-step explanation:

Here. we want to find the value of a

To do this, we are going to use the sine rule

it states that the ratio of a side and the sine of the angle that faces the side is a constant for all the sides of a triangle

From the diagram, we have that;

The angle facing a is;

180-15-105 = 60

So, we have that

a/sin 60 = 2/sin 105

a = 2sin 60/sin 105

a = 1.794 cm

Answer:

a. 16

Step-by-step explanation:

Consider these 3 values.

[tex] \sqrt{16} \\ \sqrt{27} \\ \sqrt{35} [/tex]

Factor 16,27 and 35.

[tex] \sqrt{4 \times 4} \\ \sqrt{3 \times 3 \times 3} \\ \sqrt{3 \times 3 \times 5} [/tex]

Pull out two same numbers out of the root.

[tex]4 \\ 3 \sqrt{3} \\ 3 \sqrt{5} [/tex]

Rational only when there are no square roots after simplify/evaluating.

Thus a. 16 is only rational here.

I believe it would 16 because it’s the only number that has a whole number as it’s square root(4) the other numbers have decimals

How many presents would shelia wrap in 6 hours if she wrapped 4 presents every 4 minutes?

Answers

Answer:96

Step-by-step explanation:

Well 4 presents every 4 minutes is the same thing as 1 present every 1 minute.
So now, we know that every 1 minute, she wraps 1 present.
Now, in 6 hours, there are 360 minutes so, we would simply multiply 1 present by 360 minutes which gives us the answer of 360 presents wrapped in 6 hours.

What are the solution(s) of x squared minus 4 = 0

Answers

Answer:

x=2 or x= -2

Step-by-step explanation:

x^2 - 4 = 0

x ^2  − 4  +  4  =  0 + 4  

x^2 = 4

√ ( x ^2 ) = √ 4

=  ±  2  =  { x 1 = − 2

              x 2 = 2

Answer:

X=2 or X=-2

Step-by-step explanation:

x^2 - 4 = 0

x ^2  − 4  +  4  =  0 + 4  

x^2 = 4

√ ( x ^2 ) = √ 4

=  ±  2  =  { x 1 = − 2

             x 2 = 2

Answers

Answer:

C and D, x = 5

Step-by-step explanation:

To solve this problem, you add 9.2 to both sides then divide both sides by 5.5. The Addition Property of Equality states that if two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. This is the first step to solve the problem. The Division Property of Equality states that when we divide both sides of an equation by the same non-zero number, the two sides remain equal. That is the second step to solve the problem. To solve the problem, add 9.2 to both sides, that gets us 5.5x = 27.5. Now, we divide both sides by 5.5. That gets us x = 5.

(10) Find the values of x, y, and z. The diagram is not to scale.

Answers

Answer:

y = 67 degrees

x = 86 degrees

z = 94 degrees

Step-by-step explanation:

This is easy...

38 + 56 = x

94

180 - 94 = 86

86 + 38 + 56 = 180

so x = 86 degrees

___________________

180 - 86 = 94

z = 94

___________________

94 + 19 = 113

180 - 113 = 67

67 + 94 + 19 = 180

so y = 67 degrees
