In the figure, O is the centre of a circle passing through points
A, B, C and D and ADC = 120
Find the value of x.​

Answers

Answer 1

Answer:

30 degrees

Step-by-step explanation:

The computation of the value of x is given below:

Given that

ADC = 120 degrees

So ABC = 60 degrees

As the sum of the opposite angles are 180 degrees

And ACB = 90 degrees

Now in Triangle ADC

Angle ACB + Angle ABC + x = 180 degrees

90 + 60 + x = 180

x = 30 degrees

In The Figure, O Is The Centre Of A Circle Passing Through PointsA, B, C And D And ADC = 120Find The

Fine the slope of the line perpendicular to the line graphed below

Answers

Answer:

[tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

The slope of this line is 2 because the rise from one point is 2, and the run is 1. The change in y-value is divided by the change in the x-value which is 2/1, hence, the slope of the line being 2.

The slope of the line perpendicular to the one shown below will be [tex]-\frac{1}{2}[/tex] because the slope that will result in a perpendicular line is the negative reciprocal of the original slope.

Answer:

The value of x = 28°

Step-by-step explanation:

Explanation:-

Complementary angles:-

Two angles are called Complementary angles when their measures add to 90 degrees

         ∠A + ∠B = 90°

     (x+40)° + 22° = 90°

        x + 62° = 90°

The inequality shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥  

The inequality that represents the given statement is

(1/4)n ≤ 95 + 9

The number n is n ≤ 416.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥  

We have,

Nine less than the product of a number n and 1/4 is no more than 95.

Let the number be n.

Now,

No more than means,

We have less than, greater than, and equal to.

We can use less than and equal to.

The inequality can be written as,

1/4 x n - 9 ≤ 95

(1/4)n - 9 ≤ 95

Add 9 on both sides.

(1/4)n ≤ 95 + 9

(1/4)n ≤ 104

Multiply 4 on both sides.

n ≤ 416

Thus,

The inequality that represents the given statement is

(1/4)n ≤ 95 + 9

The number n is n ≤ 416.
