4: D) 12

7: C) 63

8: A) Adjacent Angles

Step-by-step explanation:

Let's pretend the sides of a triangle are A B and C.

The third side of a triangle is always greater tham A-B and lesser than A+B. This is called the triangle inequality theorem.

For 7 and 8, we have three lines that come together at one point (adjacent angles), and the vertical angle postulate where two mirrored angles will always have the same angle.

Find the measure of angle x in the figure.

Answers

Answer:

x = 124°

Step-by-step explanation:

The polygon given is a 7-sided polygon with 7 interior angles.

Sum of all 7 interior angles of the polygon = (n - 2)*180, where n = 7, we would have the following equation:

131° + 131° + 126° + 118° + 134° + 136° + x° = (7 - 2)*180

776 + x = 900

Subtract 776 from each side

x = 900 - 776

x = 124°

Answer: 123

Step-by-step explanation:

The equation: (n-2)180

Jane corporation produces model toy cars each sells for $29 99 sense its variable cost per unit is $14 25 sense what is the break even point for Jane corporation assuming it has a fixed cost of $314800

Answers

Answer:

Break-even point in units= 20,000

Step-by-step explanation:

Giving the following information:

Selling price per unit= $29.99

Unitary variable cost= $14.25

Fixed costs= $314,800

To calculate the break-even point in units, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 314,800 / (29.99 - 14.25)

Break-even point in units= 20,000

Answers

Given:

The complex number is [tex]i^{34}[/tex].

To find:

The value of given complex number.

Solution:

We have,

[tex]i^{34}[/tex]

It can be written as

[tex]i^{34}=i^{32+2}[/tex]

Using properties of exponents, we get

[tex]i^{34}=i^{32}i^{2}[/tex] [tex][\because a^{m+n}=a^ma^n][/tex]

[tex]i^{34}=i^{4\times 8}i^{2}[/tex]

[tex]i^{34}=(i^4)^8i^{2}[/tex] [tex][\because (a^{m})^n=a^{mn}][/tex]

We know that, [tex]i^4=1,i^2=-1[/tex].

[tex]i^{34}=(1)^8(-1)[/tex]

[tex]i^{34}=(1)(-1)[/tex]

[tex]i^{34}=-1[/tex]

The value of [tex]i^{34}[/tex] is -1. Therefore, the correct option is C.

Simplify. Multiply and remove all perfect squares from inside the square roots.

hari purchased a camera for rs 1560 and sold ot at 5% loss. find hos loss amount

Answers

Answer:

[tex]SP = 1482[/tex]

Step-by-step explanation:

Given

[tex]CP = Rs. 1560[/tex] --- Cost Price

[tex]Loss = 5\%[/tex]

Required

Determine the selling price (SP)

This is calculated using:

[tex]\%Loss =\frac{CP - SP}{CP} * 100\%[/tex]

So, we have:

[tex]5\% = \frac{1560 - SP}{1560} * 100\%[/tex]

[tex]5 = \frac{1560 - SP}{1560} * 100[/tex]

Multiply through by 1560

[tex]1560 * 5 = \frac{1560 - SP}{1560} * 100*1560[/tex]

[tex]1560 * 5 = (1560 - SP) * 100[/tex]

[tex]1560 * 5 = 1560 * 100- SP * 100[/tex]

[tex]7800 = 156000- 100SP[/tex]

Collect Like Terms

[tex]100SP= 156000- 7800[/tex]

Answers

Answer:

Step-by-step explanation:

11 has 85° because it is opposite to 9

The angle that must also be measured of 85° is angle 11.

Option C is the correct answer.

What is an angle?

The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.

Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.

We have,

In the diagram,

∠9 = 85

This means,

∠9 and ∠11 are opposite angles.

And,

Opposite angles are equal.

So,

∠9 = ∠ 11 = 85

Thus,

The measure of angle 11 is also 90.
