So you find out how many triangles are in this by taking a point and making a line to another point that isn't on the same line. this one has 3 triangles. each triangle is 180*(using multiplication symbol for degree symbol).you do this to find out what the number of angles adds up to. 180* multiplied by 3 equals 540*. Then if you add up all the angles you have 400*. 540 - 400 equals 140*. So the final angle is 140*. Hope this helps!
Area: 35 inches
Perimeter: 24
Here's how I got my answer:
<u>Area:</u> The formula for the area of a rectangle is 
. So if we plug that in, it would be 
, which is 35.
<u>Perimeter:</u> You can get the perimeter by adding all the sides together, which is 
, which is 24.
Brainliest pleeease!!!!
Ok sooooooo the line is at the y intercept at (0,-50)
And if u choose two points on the graph (solid points) likeeee…. (0,-50) and (20,-30)
Use rise/ run
Soooo u go up two units and right two units soooo 2/2!!! Simplified thats what?? Thats 1!!
And so.
Y=mx+b
Plug in a few numbers….
Y=1x-50
Aaaaand the slope is moooving up (how do I know??) because from the start which is (0,-50) it goes up. So that’s why the 1 is positive. It’d be negative if it’s going the other way.
Sorry if that made no sense but moral of the story, the answer is y=1x-50
Answer:
23 1/24
Step-by-step explanation:
How i got my answer was that i did the opposite
- 82 2/3 - 59 5/8 = 23 1/24
to find what ? + 59 5/8= 82 2/3 equals to you have to do the opposite of addition which is subtraction and that will help you find the answer/sum of the problem
Answer:
79, 80, 81
Step-by-step explanation:
<u>Creating an equation.</u>
let a = first number , a + 1 = second number and a + 2 = third number
the sum of these three consecutive numbers is 240
this means that , a + ( a + 1 ) + ( a + 2 ) = 240
<u>Solving for x using the equation created.</u>
a + ( a + 1 ) + ( a + 2 ) = 240
==> remove parenthesis
a + a + 1 + a + 2 = 240
==> combine like terms
3a + 3 = 240
==> subtract 3 from both sides
3a = 237
==> divide both sides by 3
a = 79
<u>Finding the 3 numbers</u>
First number = a
a = 79 so first = 79
Second number = a + 1
a = 79 so second number = 79 + 1 = 80
Third number = a + 2
a = 79 so third number = 79 + 2 = 81
The three numbers are 79, 80 and 81
