Answer:
The perimeter of the other polygon is
Step-by-step explanation:
we know that
If two figures are similar, then the ratios of its perimeter is equal to the scale factor
Let
z---> the scale factor
x----> the perimeter of the other polygon
y----> the perimeter of the larger polygon
so
we have
substitute and solve for x
Are you talking about the angles in a triangle? Your question is not clear. I'll assume you are talking about a triangle.
Angle 1 + Angle 2 + Angle 3 = 180°
4x + 15 + 2x + 16 + x = 180°
Solve for x to find Angle 3, which in this case is the value of x.
Answer:
Step-by-step explanation:
-9= x -3 (add 3 to both sides of the equal sign)
-9+3 = x -3+3
-6 = x
solved :)
