For numbers 15-17, we need to remember that two of a triangle's angles are always acute and the third angle will allow us to classify the triangle based on its angles. now that we know this, let's look at #15. the first two angles listed are acute, and the third is an obtuse angle, therefore it is an obtuse triangle. on #16 we have three acute angles, so it is an acute triangle. #17 has two acute angles and a right angle so it is a right triangle.
on numbers 21-23, we need to know that a triangle with all congruent sides is called equilateral, a triangle with two equal sides is isosceles, and a triangle with no equal sides is called scalene. #21 shows two equal sides so it is an isosceles triangle. #22 has three equal sides so it is an equilateral triangle. #23 has no equal sides so it is scalene. hope this helped! :)
Answer:
The first one:
Equation n+(n+1) +(n+2)=36
3n+3=36
the numbers are 11, 12,13
Step-by-step explanation:
So if you plug ll for n you get 36
So if you plug 12 in for in u get 39
Then in you plug 13 in for n u get 41
I hoped that helped
Answer:
one solution
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.

Put 3 as an improper fraction
2/7 * 3/1
Multiply the numerator(2) by the other numerator(3) while multiplying the denominator(7) by the other denominator(1).
Final Answer: 6/7</span>
Answer:
There are 2 ways to find slope:
You can either take any 2 points on the graph and plug in the values for this equation: y2-y1 / x2-x1 where y2 is the value of y for the second point, x1 is the x value of the first point and so on. Or you can find the distance from any 2 points on the line by putting the amount gone up over the amount horizontally. For example from (0, -3) to (3, 0) we go up 3 units and to the right 3 units. Remember to put the amount gone up/down over the amount gone left/right. 3/3 is the slope and 3/3 is equal to 1.
the slop is 1
