Answer:
Complementary, x=78
Step-by-step explanation:
90= (x-8)+20
complementary angles add up to 90 degrees.
Original locations:
Annie: (5, -11)
Barbara: (-7, 13)
Note that the midpoint between two points (x₁, y₁) and (x₂, y₂) is
[(x₁+x₂)/2, (y₁+y₂)/2]
Therefore the meeting place has coordinates
[(5-7)/2, (-11+13)/2] = (-1, 1)
Barbara ends up at (-5, 5).
The positive difference in the y-coordinates between (-1, 1) and (-5, 5) is
5 - 1 = 4
Answer: 4
The slope of this line is -1 you find this by using the slip formula of y-y over x-x find two points on the line so I used points (-2,2) and (-1,1) plug them into the formula to get the slope of -1 hope this helps:)
The converse of the hinge theorem is also true: If the two sides of one triangle are congruent<span> to two sides of another triangle, and the third side of the first triangle is greater than the third side of the second triangle, then the included angle of the first triangle is larger than the included angle of the second .</span>
No the two side lengths are supposed to be larger than the third side length
