Answer:

x = 25

Step-by-step explanation:

Looking at the triangle we know that it is a right triangleor a 90⁰ triangle.

(2x + 15)⁰ + x⁰ = 90⁰

2x + 15⁰ + x⁰ = 90⁰

<u>2x + x</u> + 15⁰ = 90⁰

3x + 15⁰ = 90⁰

3x <u>+ 15⁰ - 15⁰</u> = <u>90⁰ - 15⁰</u>

3x = 75⁰

<u>3x / 3</u> = <u>75⁰ / 3</u>

x = 25⁰

Now plug the x value in the missing angles.

2x + 15⁰

<u>2(25⁰)</u> + 15⁰

<u>50</u><u>⁰</u><u> </u><u>+</u><u> </u><u>15</u><u>⁰</u>

65⁰

According to the sum of triangle, all angles add up to 180⁰. Even though this is a right triangle, it should add up 180⁰ in order to be a triangle.

65⁰ + 25⁰ + 90⁰ = 180⁰

Hope this helps and stay safe, happy, and healthy, thank you :) !!

Need help with math Urgent help
crimeas [40]

Answer:

Hope this helps

Step-by-step explanation:

Page 1:

I'm not sure about the first page but here is what I think.

Increased by a value of 3.

Figure 0, is most likely 2 blocks.

Starting value = 2

Growth = 3

y= 3x + 2

Fill in the values to get y.

For example, 3(52) + 2

The rate of change is 3

The y - intercept is 2

The equation of the line is y= 3x + 2

Page 2:

I assuming that the y-intercept is -5 considering it is with 0.

Looking at 10 I see 25. What times 10, subtracted by 5 will get you 25?

3

So I assume that the equation is 3x - 5. Apply this equation to 6 and 0 to see if it is correct.

3(6) - 5 = 13. Now apply this to the other values to get the rest of the chart.

Not sure what the x means in the last input

Red Line

<em>Slope:</em> 3

<em>y-intercept:</em> 4

<em>Equation:</em><em> </em>y = 3x + 4

Blue Line

<em>Slope: </em> (-1/3)

<em>y-intercept: </em>-4

<em>Equation: </em>y = (-1/3) - 4

Need help with angle theorum Lol.Expert in geometry plzz​
Over [174]

Answer:

x=71

Step-by-step explanation:

All exterior angles add up to 360

x+x-6+x+4+x+2+x+5=360

combine all the x's

5x-6+4+2+5=360

add all the numbers

5x+5=360

isolate 5x by cancelling out 5

5x+5-5=360-5

simplify

5x=355

isolate the variable

5x/5=355/5

simplify

x=71

A surveyor is studying a map of the community and is using vectors to determine the distance between two schools. On the map, th
user100 [1]

Answer:

Option C

Step-by-step explanation:

From the question we are told that

Co-ordinate of school A =(7,12)

Co-ordinate of school B =(-21,-13)

Generally the sum of the vector is mathematically represented

(A+B)=(-21-7,-13-12)

(A+B)=(-28,-25)

Generally the actual distance between the schools is mathematically given as

d=\sqrt{-28^2+-25^2}

d=\sqrt{1409}

d=37.5366 \approx 37.537m
