The answer:
according to the image the coordinates of pre image are:
A(-7, 2), B(-5, 3) C(-2, 2) and D(-5, 1)
<span>Kite ABCD is reflected over the line y = x, the main rule to find the coordinates of the images is (y, x)
for example if A(-7, 2) the image A' is A'(2, -7)
the answer is </span><span>(x,y)→(y,x); A' is at (2, −7)</span>
Answer:
96 degrees
Step-by-step explanation:
The 144 degrees is on a straight line, meaning the angle next to it inside the triangle and 144 are supplementary. They add up to 180 degrees.
Coincidentally, the other two angles plus the third, unlabeled angle will add up to 180 degrees as well, meaning that the the 48+x = 144 degrees (according the property of equality, which is if a=b and b=c, then a=c). Solve for x from there:
x = 144-48
x = 96
A scalene triangle is a triangle that has 3 sides that are all different lengths.
Let these letters represent the problem:
a = 8.7
b = side 2
c = side 3
P = 54.6
To find the perimeter, we just need to add all the sides [ P = a + b + c ]
So, put what we have in the formula above.
54.6 = 8.7 + b + c
Best of Luck!
