Answer:

1. Two angles are called complementary when their measures add to 90 degrees.

2. Two angles are called supplementary when their measures add up to 180 degrees.

Step-by-step explanation:

Answer:

x= 1.6 degrees

Step-by-step explanation:

to find the missing angle 180 degrees - 151 degrees

29° is the missing angle at the bottom ryt of the triangle.

all angles in triangle add upto 180°

so, 20x-3°+11x-1°+29°= 180°

31x=180°-25°

x= 1.6°

A polygon with three edges and three vertices is called a triangle.

x=1.6° is its value.

Based on the lengths of its sides, triangles can be categorized into one of three groups: Scalene. Isosceles. Equilateral.

The trigon, a 3-sided polygon, is sometimes (though not often) referred to as a triangle. Every triangle has three sides and three angles, some of which might be the same.

The triangle's angles are created by joining its three sides end to end at a single point. The sum of the three angles of the triangle is 180degrees.

To identify the omitted angle between 180 and 151 degrees

The triangle's bottom right corner lacks a 29° angle.

triangle's angles sum up to 180°

so, 20x-3°+11x-1°+29°= 180°

31x=180°-25°

x =1.6 degree

Answer: The perimeter is 30ft.

Step-by-step explanation:

Let's define:

L = length of the longer side.

S = length of the shorter side.

P = perimeter

we know that for a common rectangle:

P = 2*S + 2*L

We aso know that:

L = 2ft + (1/3)*P

S = (1/10)*P

L = S + 9ft.

So we have a system, let's find the perimeter only using this system (So i will ignore the equation for the perimeter of a rectangle)

First, we can replace the third equation in the first equation, now we have a system with only two equations:

S + 9ft = 2ft + (1/3)*P

S = P/10

Now we can replace the second equation in the first equation, and get:

P/10 + 9ft = 2ft + P/3

Now let's solve this for P.

9ft - 2 ft = P/3 - P/10

7ft = P( 1/3 - 1/10) = P*( 10/30 - 3/30) = P*(7/30)

(30/7)*7ft = P = 30ft.

The perimeter is 30ft.

Answer:

It is rational because the answer is -3

Step-by-step explanation:

-3 can be writen as a fraction so it is a rational number.

Answer:

That is a rational number

Step-by-step explanation:

[tex]\sqrt{9}[/tex] = 3.

Therefore, -[tex]\sqrt{9}[/tex] = -1(3) = -3.

-3 is RATIONAL.  

m = -9/8 (slope)

This means 9 down, and 8 right.

_________________________

To calculate the slope, just use this formula:

[tex] m \: = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

y2 or x2 can also be thought of as just y and x. This is because only a slope, and one point is needed to solve for another point that fits on the line.

Given point 1 : (-2,6), and point 2 : (6,-3).

We can find slope by: point 2y - point 1y/ point 2x - point 1x =

(-3-6)/(6-(-2)) = (-9)/(8) = -9/8

Answer:

The answer is C.-216

Step-by-step explanation:

Answer:

C.)-216

Step-by-step explanation:

Since -6 is negative, it makes it become a positive when multiplyed, and then back to a negative when multiplyed again.

It depends on the problem, but here's an example.

Let's say you earn $20 an hour and you already have $100 in the bank. If you work x hours, then you'll have 20x additional dollars on top of the $100 you already have. So in total you have y = 20x+100 dollars

x = number of hours worked

y = total amount of money

This does not take into account taxes or other kinds of fees/deductions from your paycheck.

Comparing y = 20x+100 with y = mx+b, the slope is m = 20 and the y intercept is b = 100.

The slope tells us how fast the money increases (since it's the rate of change). In this case, slope = rise/run = 20/1 meaning that for each hour, the money goes up by $20.

The y intercept is the starting value which in this case is $100. If you worked x = 0 hours, then you'll still have that $100.

Answer: [tex]n=\frac{11}{10}[/tex]



Step-by-step explanation:

[tex]\frac{3n}{7}=\frac{33}{70}[/tex]

[tex]\frac{210n}{210}=\frac{231}{210}[/tex]

[tex]n=\frac{11}{10}[/tex]

Lol this question seems simple for a person coming from Calculus only to increase my confidence ; )

3n/7 = 33/70

So to solve this equation , all you have to do is cross multiply the fractions.

3n*70 = 33*7

210n = 231

n = 231 / 210 = 11/10

n = 11/10

Answer:

x=5

Step-by-step explanation:

7 (x-8)=2x-31

Distribute the 7 to the x and -8 (basically multiple 7 with the x and -8)

7x-56=2x -31

Drag the 2x over to the other subtracting it from 7x.

7x-2x-56=-31

5x-56=-31

Drag the 56 to the other side and add it to -31

5x= -31+56 (or 56-31)

5x= 25

Divide 5x from 25 to get your X

x=25/5

x=5

Answer:

5 units

Step-by-step explanation:

From the coordinates, we have;

x1 = -5

x2 = -1

y1 = 5

y2 = 2

Now,from the distance formula, distance is;

d=√((x2 - x1)²+(y2 - y1)²)

Plugging in the relevant values, we have;

d = √((-1 + 5)²+(2 - 5)²)

d = √(16 + 9)

d = √25

d = 5
