Answer with Explanation:
It is Given that Nathan cut a rectangular tile in half for his kitchen floor design.
As,the cut is made along a diagonal from one vertex to another vertex.
If you cut rectangle along through any of two diagonals,
you will get two triangles which are congruent.
→∵ Opposite sides are Congruent.
→Diagonal is common.
So,two triangles will be congruent by SAS.
Triangles categorized as
1. Scalene triangle
2. Right Triangle
The Two Triangles named in a single way as Scalene Right Triangle.

First, we find the area of the circle.
A = pi * r^2
A = pi * (1 cm)^2
A = pi cm^2
The area of the circle is pi cm^2.
The area of the triangle is also pi cm^2.
Now we use the area of a triangle.
A = (1/2)bh
(1/2)bh = A
(1/2)(3 cm)h = pi cm^2
(3 cm)h = 2pi cm^2
h = (2/3)pi cm
The exact height is
If you want an approximate height, then it is 2.09 cm.

Answer:
y= -4x+7
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Let's find the gradient of the line first.
Using the above formula,
Susbt. m= -4 into the equation:
y= -4x +c
Subst. a coordinate to find c.
When x=3, y= -5,
-5= -4(3) +c
-5= -12 +c
c= 12 -5
c=7
Thus the equation of the line is y= -4x +7.
