Answer:
x=20 cm
Step-by-step explanation:
Let x be the length of equal sides.
Area of triangle=
We have to find the values of x.
We know that
Area of right triangle=
Where b=Base of triangle
h=Height of triangle
Using the formula
Area of right triangle=





Hence, the value of x=20 cm
Formula of a midpoint is ((x1+x2)/2, (y1+y2)/2)
((13+-17)/2, (-24+-6)/2)
((-4)/2, (-30)/2)
(-2,-15,)
So the midpoint is (-2,-15)
Answer:
The area of this shape is 252.
Step-by-step explanation:
Cut the right piece of the shape into a triangle of 90 degrees, which makes the shape divided into 2 triangles and 1 rectangle.
9 x 13 = 117 (rectangle part)
15 x 9 = 135, 135/2 = 67.5
15 x 9 = 135, 135/2 = 67.5
67.5 + 67.5 + 117 = 252
A=1
B= -1
C= 1/4
B^2-4ac
(-1)^2 -4(1)(1/4)
1 -1
0 = 1 solution
