Mathematics
1 answer:
xz_007 [3.2K]3 years ago

Answer:

Angle BCA (48 degrees) is an inscribed angle and the arc it intercepts (arc AB) is twice the inscribed angle.  So arc AB is 96 degrees.

Angle AOB is a central angle and angle BPA consists of 2 tangents.

When a central angle (2 radii) intersects with 2 tangents, the 2 angles formed sum to 180 degrees.  (Angle BOA + Angle BPA = 180 degrees).

Angle BOA = arc AB = 96 degrees.

Angle BOA + angle APB = 180

Therefore, Angle APB = 84 degrees.

Are rectangular garden has a perimeter of 280 feet the north side of the garden is 90 feet what is the length of the inside of t
attashe74 [19]

The length of the inside of the garden is<u> 50 feet.</u>

What is perimeter ?

A perimeter is a closed path that covers, surrounds, or outlines a two-dimensional shape or length. The circumference of a circle or an ellipse is its perimeter.

There are various practical applications for calculating the perimeter. A calculated perimeter is the length of fencing needed to completely encircle a yard or garden. The perimeter (circumference) of a wheel/circle describes how far it will roll in one revolution. Similarly, the amount of string wrapped around a spool is proportional to the spool's perimeter; if the string length were correct, it would equal the perimeter.

Given :

The rectangular garden has a perimeter of 280 feet

breadth = 90 feet

Let the length be x.

Therefore according to the question,

2( 90 + x ) = 280

=> 90+ x = 140

=> x = 50

How do you write this in standard form? (6-7i)/(1-2i)
xenn [34]
\frac { \left( 6-7i \right)  }{ \left( 1-2i \right)  } \cdot 1\\ \\ =\frac { \left( 6-7i \right)  }{ \left( 1-2i \right)  } \cdot \frac { \left( 1+2i \right)  }{ \left( 1+2i \right)  } \\ \\ =\frac { 6+12i-7i-14{ i }^{ 2 } }{ 1+2i-2i-4{ i }^{ 2 } }

\\ \\ =\frac { 6+5i-14\left( -1 \right)  }{ 1-4\left( -1 \right)  } \\ \\ =\frac { 6+5i+14 }{ 1+4 } \\ \\ =\frac { 20+5i }{ 5 } \\ \\ =\frac { 20 }{ 5 } +\frac { 5i }{ 5 } \\ \\ =4+i

In this graph what is the slope of the line?
sashaice [31]

Answer:

The slope of the line is 10

Step-by-step explanation:

To find the slope, simply identify 2 points on the line. I chose: (1,10) and (2,20)

20-10=10

2-1=1

The slope of the line is 10

To check this answer, just multiply X with 10 and you will always get Y!
