Solve for xx. Round to the nearest tenth, if necessary.

jasenka [17]

Step-by-step explanation:

S+T+U=180°{sum of angle of triangle}

68°+90°+U=180°
U=180-158°
U=22°

sin theta= p/h

sin22°=x/83

o.37=x/83

x=0.37×83

x=30.71

x=31

The other leg is 12cm long.

Step-by-step explanation:

Given,

Hypotenuse = c = 15cm

One leg = a = 9cm

Other leg = b

As the triangle is right angled, therefore, using Pythagoras theorem;

$a^2+b^2=c^2\\(9)^2+b^2=(15)^2\\81+b^2=225\\b^2=225-81\\b^2=144\\$

Taking square root on both sides;

$\sqrt{b^2} =\sqrt{144} \\b=12\ cm$

The other leg is 12cm long.
