Answer:
S(1) = 1
S(n) = S(n-1) + n
Where S(n) is the sum from 1 till n
And,
S(n-1) is the sum from 1 till n-1

Answer:
a) 625; 625; right triangle
b) 205; 256; obtuse triangle
Step-by-step explanation:
The squares are values found in your memory or using a calculator. It is straightforward addition to find their sum.
<h3>left side</h3>
7² +24² = 49 +576 = 625
25² = 625
The sum of the squares of the short sides is the square of the long side, so this is a right triangle.
__
<h3>right side</h3>
6² +13² = 36 +169 = 205
16² = 256
The long side is longer than is needed to form a right triangle, so the largest angle is more than 90°. This is an <em>obtuse triangle</em> (as shown).
Answer:
45
Step-by-step explanation:
divide 300 by 100 then multiply it by 15 to find how many people makes 15% of 300
300 ÷ 100 = 3 ➡ 3×15 = 45
