Answer 1

Answer:

$h=\sqrt{1.44}\\h = 1.2$

Step-by-step explanation:

Base of the triangle on the left = 0.5

Use pythagorean theorem

$a^{2} + b^{2} = c^{2}$

Substitute

$0.5^{2} + b^{2} = 1.3^{2}$

$b^{2} = 1.3^2 - 0.5^2$

$b^2 = 1.44$

$b = \sqrt{1.44}$

$b = 1.2$

in this case b is the height

so

$h=\sqrt{1.44}\\h = 1.2$
