9 less than a number is <em><u>9 - n</u></em>

Where n is that number

It says less than so you want to subtract.
an number with be represented by the variable n:
n-9
it isn't 9 minus n because that would be nine less a number(9-n)
so your answer is:
<span>n-9</span>

<h3>What are Triangles?</h3>

A triangle is a 3-sided polygon with three sides and three angles. The sum of all its interior angles is 180 degrees. Some special triangles are:

Isosceles triangle: has 2 equal base angles.
Equilateral triangle: has three equal angles, each measuring 60 degrees.
Right Triangle: Has one of its angles as 90 degrees, while the other two are acute angles.

5. m∠C = 180 - 50 - 35 [triangle sum theorem]

m∠C = 95°

6. m∠C = 180 - 25 - 85 [triangle sum theorem]

m∠C = 70°

7. The other acute angle in the right triangle = 180 - 90 - 25 [triangle sum theorem]

The other acute angle = 70°

8. m∠C = 180 - 55 - 55 [isosceles triangle]

m∠C = 70°

9. m∠C = 60° [equilateral triangle]

10. Measure of the exterior angle at ∠C = 50 + 60

Measure of the exterior angle at ∠C = 110°

11. m∠B = 115 - 45
