One of the unknown adjacent angle measures 48.3 degrees.

The adjacent angles are next to each other and hence are calculated by performing addition of the constituent angles. Let us assume the unknown adjacent angle be x.

Forming the equation based on x, adjacent angles and it's sum

104.7 + x = 153

Rewriting the equation as per the x

x = 153 - 104.7

Performing subtraction on Right Hand Side of the equation to find the value of x

x = 48.3 degrees

Thus, the measure of the adjacent angle is 48.3 degrees.

The amount received by Charis on Simple interest in 2 years will be $8.4

What is Simple Interest?

The process of figuring out how much interest will accrue on a given principal sum of money is known as simple interest (S.I.).

It's formula is given by S.I. = PRT/100  where P = principle amount

R= rate and T = time.

Main Body:

P= $140

R= 3%

T= 2 years

so S.I. = 140*2*3/100

4, 7/4, -1/2, -11/4, is Arithmetic progression.

What is Arithmetic progression ?

An arithmetic progression or arithmetic sequence ( AP ) is a sequence of numbers such that the difference between the consecutive terms is constant.

Here the series is given

4, 7/4, -1/2, -11/4,.....

In series, take 1st and 2nd terms to know common difference.

the common difference is = 7/4 - 4

                                              = (7 - 16) / 4 = -9/4

Now, take 3rd and 2nd term

common difference = -1/2 - 7/4

                                 = (-2 - 7) / 4 = - 9/4

so, we get the common difference is -9/4.

By that we can clearly say that given sequence of series is a Arithmetic sequence.

What is circle equation?

 For all values of g, f, and c, the general equation of any type of circle is written as x2 + y2 + 2gx + 2fy + c = 0. The collection of all points in a plane that maintain a fixed, finite distance r from a fixed point is known as a circle. O = (a,b). The definition of a circle on the coordinate plane can be expressed using the equation of a circle. The equation is where r is the radius and if the centre of the circle is at the origin of the coordinate plane.

Here the given circle equation is,

The equation of a line for y-intercept and the coordinate point is y=3x-1.

Given that, y-intercept is -1 and the line passes through the point (3, 8).

In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.

Put, c=-1 and (x, y)=(3, 8) in y = mx+c, we get

8=m(3)-1

⇒ 3m=9

⇒ m=3

Substitute c=-1 and m=3 in y = mx+c, we get

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.

Here it is given that the measure of the rectangle is 238 cm and 435cm.

The Raegan creates a mural that is 27cm.

Perimeter = 2(length + breadth)

Earlier the length is 238cm and the breadth is 435cm.

Now replace the breath 435cm to 27cm.

length = 238cm

breadth = 27cm

The number of times Aarf the Dog bark for 15 seconds if the dog starts barking at midnight and stops at 1:01 AM is 91.5 times

Total time of barking and silence = 15 seconds + 25 seconds

Convert hours and minutes to seconds

1 hour 1 minutes = 61 minutes × 60 seconds

Number of times Aarf the Dog bark for 15 seconds = Total hours Aarf dog barks / Total time of barking and silence
