Question

Can someone help me out with this problem? Thank you!

Answer 1

three (3).

Explanation:

H=O+A

c^2=5^2+12^2

c^2=25+144

c^2=169

c=√169

c=13

Answer 2

`\qquad\qquad\huge\underline{{\sf Answer}}`

Let's calculate the value of c using Pythagoras theorem ~

`\qquad \sf  \dashrightarrow \: c {}^(2) = a {}^(2) + {b}^(2)`

`\qquad \sf  \dashrightarrow \: c {}^(2) = {5}^(2) + {12}^(2)`

`\qquad \sf  \dashrightarrow \: c = √(25 + 144)`

`\qquad \sf  \dashrightarrow \: c = √(169)`

`\qquad \sf  \dashrightarrow \: c = 13 \: units`
