Answer:
x = 20
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= ( cross- multiply )
9x = 180 ( divide both sides by 9 )
x = 20
By taking x as subject the formula becomes x = (v² - u²)/2a.
<h3>What is Equation?</h3>
An equation is a mathematical statement with an 'equal to=' symbol between two expressions that have equal values.
Here given equation:
v² = u² + 2ax
2ax = v² - u²
x = (v² - u²)/2a
Thus, by taking x as subject the formula becomes x = (v² - u²)/2a.

Answer:
12
Step-by-step explanation:
The sum of the measures of the interior angles is given by:
n:sides of the polygon
And in a convex polygon the sum of the exterior angles sums 360°
Then
You just solve it and the answer is 12.
