Question : 27

Total: 40

Solution:

Concept

Side

C

is always the side opposite to the right angle

\; \Rightarrow 5^2+t^2=13^2

\;25+t^2=169

\;t^2=169-25

\;t^2=144

Take the square root of both sides to get rid of the power 2

\; \sqrt{t^2} = \sqrt{144}

\;t=12

NOTE: The result of a square root is simply the number when multiplied by itself will give the number you are calculating the square root of

Thus

\sqrt{144}=12

since

12 \times 12

gives 144
