145 cause 40+85+90 equals 215 n then subtract that from 360

Here's the solution ~
As we know, we can calculate the circumference of a circle in terms of its diameter as :

where, c = circumference and d = diameter
And also, circumference of circle is terms of radius (r) is :

Answer:
x = -2
Step-by-step explanation:
2 (3x+11)=10
Divide each side by 2
2/2 (3x+11)=10/2
3x+11 = 5
Subtract 11 from each side
3x+11-11 = 5-11
3x = -6
Divide each side by 3
3x/3 = -6/3
x = -2
Answer:
The sides of the triangles adjacent to the center of dilation will be collinear. The third sides of the pre-
image and image will be “parallel”
The vertex used as the center of dilation will be in “the same location in both triangles”
