Find the values of x and y

Mathematics
1 answer:
const2013 [10]3 years ago
7 0

Answer:

x = 79 y = 22

Step-by-step explanation:

x would be the same as the other side so 79 * 2 would be 158. A whole triangle is 180. 180 - 158 = 22

What are you building when you use a distance formula
kirill115 [55]

Answer:

See below  

Step-by-step explanation:

In math, the distance formula gives us the distance between two

points, (x₁, y₁) and x₂, y₂):

d = \sqrt{(x _{2}-x_{1})^{2} +(y _{2}-y_{1})^{2}}

For example, in the triangle below, the distance between the points (1,5) and (-2, 1) is  

d = \sqrt{(1 - (-2))^{2} +(5-1)^{2}}

= \sqrt{3^{2} +4^{2}}

= \sqrt{9 + 16}

= \sqrt{25}

= 5

You are really using Pythagoras' Theorem to find the distance.

When using the distance formula, you are building a right triangle whose hypotenuse connects two given points.

Please help me let me know how you got the answer

Area of building is 3,84,000m^3 .

<u>Step-by-step explanation:</u>

Here we have , a figure in given below picture where we have to find volume of this office building , Let's find out:

If we look closely we see that it's basically cuboid with dimensions 50 m by 110 m by 70 m . But there's one small cuboid sliced off from this cuboid with dimensions 50 m by 10 m by (110-90) m i.e.  50 m by 10 m by 20 m .

Area of building = Area of larger cuboid - Area of smaller cuboid

Area of cuboid = length(width)(breadth)

⇒ Area of building = Area of larger cuboid - Area of smaller cuboid

⇒ Area = (50(110)(70))m^3 - (50(10)(20))m^3

⇒ Area = 3,85,000m^3 - 10,000m^3

⇒ Area = 3,84,000m^3

Therefore, Area of building is 3,84,000m^3 .

Select the correct answer. What are the intercepts of y = 4x − 2?
Goshia [24]

Answer:

A  is the correct answer

Step-by-step explanation:

To answer this you need to find the value for x that makes the y value zero.

and the value for y when x is zero.

There are 2 intercepts on for a linear equation.  One x-intercept (where the graph crosses the x-axis) and one y-intercept (where the graph crosses the y-axis).

Step 1:  

The x-intercept is found by setting 'y' equal to zero and solving the equation.

0 = 4x - 2         solve this...

  2 = 4x            (add 2 to both sides)

0.5 = x                (divide both sides by 4 to get x by itself)

So the x-intercept is at the point (0.5. 0)

Step 2:  The y-intercept if found by setting 'x' equal to zero and solving

y = (0)x - 2  

   

   y = -2        

So the y-intercept is at the point (0, -2)
