2 answers:

8 0

To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360°if the angle is measured in degrees or 2π if the angle is measured in radians. Example 1: Find a positive and a negative angle coterminal with a 55°angle. A −305°angle and a 415°angle are coterminal with a 55°angle.

A four-sided shape has four congruent angles and sides. Which quadrilateral could it be? A. quadrilateral B. trapezoid C. square

Gnoma [55]

Answer:

C. square

Step-by-step explanation:

Congruent means "the same" (having the same shape and size).

Any four-sided, 2-dimensional shape with straight sides is called a quadrilateral.

There are 6 special types of quadrilaterals:

Rectangle

Opposite sides are parallel and equal in length
All interior angles are 90°

Square

All sides are equal in length
All interior angles are 90°

Rhombus

All sides are equal in length
Opposite sides are parallel
Opposite angles are equal

Parallelogram

Opposite sides parallel and equal in length
Opposite angles are equal

Trapezoid

One pair of opposite parallel sides

Isosceles Trapezoid

One pair of opposite parallel sides
One pair of non-parallel sides equal in length
Two pairs of equal base angles

Kite

Two pairs of adjacent sides equal in length
The angles included between the sides of differing lengths are equal

Conclusion

A four-sided shape that has four congruent angles and sides is a SQUARE.

HELP FOLLOW PEMDAS RULES 6 ÷ 2(1+2) = GOOD LUCK :)

inysia [295]

Answer:

Step-by-step explanation:

PEMDAS IS

parentheses

Exponents

Multiply and divide

Addition and subtraction

First you start with the parentheses so

1 + 2 = 3

Now you have 6/2 x 3

Multiply and divide means you either divide or multiply what ever comes first going left to right

6/2 = 3

3 x 3 = 9

If it was reversed we’d have

2 x 3/6 which would be

6/6 = 1

Draw the graphs of the pair of linear equations : x + 2y = 5 and 2x - 3y = -4 Also find the points where the lines meet the x -

aliina [53]

Answer:

(1, 2)

Step-by-step explanation:

Given the equation of the lines x + 2y = 5 and 2x - 3y = -4

First we need to make x the subject of the formulas

For x+2y = 5

x = 5 - 2y ... 1

For 2x - 3y = -4

2x = -4+3y

x = (-4+3y)/2 ... 2

Equate 1 and 2

5 - 2y = (-4+3y)/2

2(5-2y) = -4+3y

10 - 4y = -4+3y

-4 -3y = -4-10

-7y = -14

y = 14/7

y = 2

Substitute y = 2 into 1

x = 5 = 2y

x = 5 - 2(2)

x = 5 - 4

x = 1

Hence the point where the lines meet will be at (1, 2)
