Find the tangent of ∠I.

Nady [450]

Answer:

tanI = $\frac{\sqrt{70} }{5}$

Step-by-step explanation:

We require to calculate GH using Pythagoras' identity in the right triangle.

GH² + GI² = HI²

GH² + 5² = ( $\sqrt{95}$ )²

GH² + 25 = 95 ( subtract 25 from both sides )

GH² = 70 ( take square root of both sides )

GH = $\sqrt{70}$

Then

tanI = $\frac{opposite}{adjacent}$ = $\frac{GH}{GI}$ = $\frac{\sqrt{70} }{5}$

If in a right triangle, the given legs are a = 10 and b=16, then by using the Pythagorean Theorem find the hypotenuse, c.

Reika [66]

Answer:

$c=2\sqrt{89}$

Step-by-step explanation:

Pythagorean theorem is:

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

$c^{2}=10^{2}+16^{2} \\c^{2} =100+256\\c^{2}=356\\c=\sqrt{356} \\c=2\sqrt{89}$
