With the coordinates of the vertices of triangle ABC at A(-1, 3), B(-5, -1), C(3, -1), we have;
- Triangle ABC is an isosceles triangle
<h3>How can the type of a given triangle be found?</h3>
Taking the vertices of ∆ABC as found in a similar question online as A(-1, 3), B(-5, -1), C(3, -1), calculating the lengths of the sides of the triangle gives;
AB = √((-1 - (-5))² + (3 - (-1))²) = 4•√2
AC = √((-1 - 3)² + (3 - (-1))²) = 4•√2
BC = √((-5 - 3)² + (-1 - (-1))²) = 8
AB = AC = 4•√2
- Triangle ABC is an <u>isosceles triangle</u> by the definition of isosceles triangles.
<em>(AB)² + (AC)² =</em> (4•√2)² + (4•√2)² = 64 = (BC)²
Therefore;
(BC)² = (AB)² + (AC)²
Which indicates that triangle ABC is an isosceles right triangle.

#SPJ1
2(x+10)=3x-30
2x+20=3x-30
x=50
Therefore, x=50 is your answer.
Remember that vertical angles, angles opposite from each other, have the same degree. That is why you can set up 2(x+10)=3x-30.
Answer:
Step-by-step explanation:
Let the two numbers be 2x and 3x.
According to the question,
2x+3x=45
5x=45
x=45/5
x=9
so th required numbers are 18 and 27 as
2x=2*9=18
3x=3*9=27
1 - $0.25 2 - $0.37 3 - $0.49 4 - $0.61 5 - $0.73 6 - $0.85 7 - $0.97
7 muffins would equal $0.97
