Question

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

Answer 1

Answer:

three (3).

Step-by-step 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 ~

$\qquad \sf  \dashrightarrow \: c {}^{2} = a {}^{2} + {b}^{2}$

$\qquad \sf  \dashrightarrow \: c {}^{2} = {5}^{2} + {12}^{2}$

$\qquad \sf  \dashrightarrow \: c = \sqrt{25 + 144}$

$\qquad \sf  \dashrightarrow \: c = \sqrt{169}$

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