Answer:
- Angles 1 & 2 are congruent/equal in measure
- Angles 1 & 3 are supplementary (I'm sure of this part) because they are adjacent and add up to 180° (I'm sure of this part, but I don't know what exact wording they are looking for in your problem)
- Angles 2 & 4 are supplementary (same reasoning as angles 1 &3)
Step-by-step explanation:
Angles in a trapezoid that are adjacent are always either congruent (meaning they have the same measure) or they are supplementary (meaning you take one small angle measuring less than 90° - known as an acute angle - and one large angle measuring more than 90° - known as an obtuse angle - and when you add the two angles together they will always equal 180° - which means they are supplementary).
I believe it’s b: right triangle
4+3x = (k+2)x + 8
4+2+3x = (k+2)x + 8 - 2
6+3x = (k+2)x + 6
then 3x = k+2
so k = 3X-2
Answer:
B ( -1, -8)
Step-by-step explanation:
A ( -7, -6)
midpt (-4, -7)
Equation:
(x + 3, y - 1)
Solve for B:
(-4, -7)
(x + 3, y - 1)
( -1, -8)
Communitive property is the property that allows you to move the numbers around in addition and multiplication.
For example:
(addition) 1 + 2 = 2 + 1
(multiplication) 3 x 4 = 4 x 3
This property cannot be used in division or subtraction
