Answer:

77°

Step-by-step explanation:

From the question given above, the following data were obtained:

Cos α = 0.93

Sine θ = 0.26

Tan β = 0.84

α + β + θ =?

Next, we shall determine the value of α. This can be obtained as follow:

Cos α = 0.93

Take the inverse of Cos

α = Cos¯¹ 0.93

α = 22°

Next, we shall determine the value of θ. This can be obtained as follow:

Sine θ = 0.26

Take the inverse of Sine

θ = Sine¯¹ 0.26

θ = 15°

Next, we shall determine the value of β. This can be obtained as follow:

Tan β = 0.84

Take the inverse of Tan.

β = Tan¯¹ 0.84

β = 40°

Finally, we shall determine the value of α + β + θ . This can be obtained as follow:

α = 22°

θ = 15°

β = 40°

α + β + θ = 22 + 40 + 15

α + β + θ = 77°

In the figure above, PQRS is a circle. If PQT and SRT<br>are straight lines, find the value of x.
Elena L [17]

Given:

PQRS is a circle, PQT and SRT  are straight lines.

To find:

The value of x.

Solution:

Since PQRS is a circle, PQT and SRT  are straight lines, therefore, PQRS isa cyclic quadrilateral.

We know that, sum of opposite angles of a cyclic quadrilateral is 180 degrees.

m\angle SPQ+m\angle QRS=180^\circ

81^\circ+m\angle QRS=180^\circ

m\angle QRS=180^\circ-81^\circ

m\angle QRS=99^\circ

Now, SRT  is a straight line.

m\angle QRT+m\angle QRS=180^\circ             (Linear pair)

m\angle QRT+99^\circ=180^\circ

m\angle QRT=180^\circ-99^\circ

m\angle QRT=81^\circ               ...(i)

According to the Exterior angle theorem, in a triangle the measure of an exterior angle is equal the sum of the opposite interior angles.

Using exterior angle theorem in triangle QRT, we get

m\angle PQR=m\angle QRT+m\angle QTR

x=81^\circ+22^\circ

x=103^\circ

Therefore, the value of x is 103 degrees.

What is the solution to the equation?
AleksandrR [38]

Solution of the equation: x=6\frac{1}{2}

Step-by-step explanation:

The equation that we have to solve in this problem is:

13\frac{3}{4}+x=7\frac{1}{4}

The first step to do is to rewrite the mixed fractions as improper fractions. We have:

13\frac{3}{4}=\frac{13\cdot 4+3}{4}=\frac{52+3}{4}=\frac{55}{4}

And

7\frac{1}{4}=\frac{7\cdot 4+1}{4}=\frac{29}{4}

So the equation becomes

\frac{29}{4}+x=\frac{55}{4}

Now we multiply by 4 each term on both sides, and we get

29+4x=55

Now we subtract 29 from both sides,

4x=55-29=26

And finally, we divide both sides by 4:

x=\frac{26}{4}=\frac{13}{2}=6\frac{1}{2}

HELP!!!!!!!!!!!!!!!!!!!!! Do all real numbers have a decimal expansion? Select each correct answer. Some numbers, such as 1 10 ​
ankoles [38]

Answer:

1. Some numbers, such as \frac{1}{10}, have a decimal expansion that terminates.

2. All real numbers have a decimal expansion.

5. Some numbers, such as \frac{1}{18}, have a decimal expansion that repeats but does not terminate.

Step-by-step explanation:

According to the options, we have,

1. Some numbers, such as \frac{1}{10}, have a decimal expansion that terminates.

It is correct as the decimal expansion of \frac{1}{10} is 0.1, which terminates.

2. All real numbers have a decimal expansion.

This is also correct as both rational and irrational numbers can be written in decimal form.

3. Some numbers, such as \sqrt{13} do not have a decimal expansion

This is not correct as \sqrt{13}=3.605551275 i.e. it has a decimal expansion.

4. Only some real numbers have a decimal expansion.

It is not correct as 2 is correct.

5. Some numbers, such as \frac{1}{18}, have a decimal expansion that repeats but does not terminate.

It is correct as \frac{1}{18}=0.0555555.., which is non-terminating decimal expansion.

So, the correct options are,

1. Some numbers, such as \frac{1}{10}, have a decimal expansion that terminates.

2. All real numbers have a decimal expansion.

5. Some numbers, such as \frac{1}{18}, have a decimal expansion that repeats but does not terminate.
