Answer:
Step-by-step explanation:
The length of this triangle is 10 squares
and the width is 4 squares
The diagonals divide the rectangle into four triangles
These traingles are isoceles
Each two triangles facing each others are identical
<B = 90 degree
B = alpha + Beta
Let Beta be the angle next alpha
The segment that is crossing Beta is its bisector since it perpendicular to the diagonals wich means that:
Beta = 2x
Then B = alpha + 2x
90 = alpha +2x
90-alpha = 2x
x = (90-alpha)/2
Answer:
(4,5)
Step-by-step explanation:
The vertex is written in vertex form.
y = a(x - b)^2 + c
Vertex: (b,c) Notice the sign change on b.
So for your equation, you get (4,5) No sign change on the 5.
