Mathematics

Andreyy893 years ago

Answer:

117°

Step-by-step explanation:

Angle of straight line is 180°

Angles in a triangle add up to 180°

starting at right

180 - 101 = 79° at right side angle in triangle

now solving left side angle

180 - 38 - 79 = 63°

now solving x using left side angle, must add to 180°

x + 63 = 180°

x = 117°

Answer:

117

Step-by-step explanation:

101=38+(180-x)

101-38=180-x

63=180-x

x=180-63=117

See below for the solution to the systems of equations

<h3>How to solve the systems of equations?</h3>

<u>System of equations 1</u>

Here, we have

y = -5x/3 + 3

y = x/3 -3

We start by plotting the graph of both equations

Next, we write out the point of intersection of the equations

See attachment for the equation of the system

From the attached graph, the point of intersection of the equations is (3, -2)

Hence, the solution to the system is (3, -2)

<u>System of equations 2</u>

Here, we have

y = 4x + 3

y = -x -2

We start by plotting the graph of both equations

Next, we write out the point of intersection of the equations

See attachment for the equation of the system

From the attached graph, the point of intersection of the equations is (-1, -1)

Hence, the solution to the system is (-1, -1)

Use the distance formula to find distance between two points. Need help on this ASAP.
astra-53 [7]

Answer:

a) 20 units

b) 2 √10 units

c) 2 √17 units

Step-by-step explanation:

The distance formula is;

D = √(y2-y1)^2 + (x2-x1)^2

a) D = √(-7-9)^2 + (-7-5)^2

D = √256 + 144

D = √400

D = 20

b) D = √(10-8)^2 + (9-2)^2

D = √(2)^2 + 6^2

D = √4 + 36)

D = √40

D = 2 √10 units

c) D = √(1 + 7)^2 + (-8+10)^2

D = √(64 + 4)

D = √68

D = 2 √17 units

Mrs. Delgado needs to buy 160 begonias for her flowerbed. At the prices shown, how much would she save if she bought them by the
wlad13 [49]

Answer:

\$46.40

Step-by-step explanation:

step 1

Find out the price of 160 begonias, if she bought them separately

160(\$1.79)=\$286.40

step 2

Find out the price of 160 begonias, if she bought them by the flat

Remember that

One flat are 20 plants

so

For 160 plants are needed

160/20=8 flat

8(\$30)=\$240

step 3

Find out the difference

\$286.40-\$240=\$46.40
