Answer:
r = 46
Step-by-step explanation:
as in the attachment, have created the CEF triangle by stretching lines.
hope it helps:)
good luck:)
Circumference of circle = π x d
diameter = 3x2= 6m
3.14 x 6 = 18.84m (circumference)
Area of a circle = π x r x r
=3.14 x 3 x 3
=28.26m2 (area)
We have to know the angle that is not labelled. (lets call it y)
9x + y= 180
and the sum of the angles of a triangle is 180
5x + (9+x) + y=180
2 simultaneous equations
Hello,
y=3x+b is parallele to y=3x-10
In order to determine b, we must know something else.
Answer:
Firstly find the area of the square and then the area of the two triangles and then plus it. That's what I think I tried
