Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>30</u></em></h2>
Step-by-step explanation:
<em><u>According</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>figure</u></em><em><u>, </u></em>
54° + 3x+36° = 180° <em>[</em><em>Linear</em><em> </em><em>pair</em><em>]</em>
=> 3x + 90 = 180
=> 3x = 180 - 90
=> 3x = 90
=> <em><u>x = 30 (Ans)</u></em>

Answer:
(3) 12
Step-by-step explanation:
Let x represent the length of leg XY. Then the length of YZ is x/2 and the area of the right triangle is ...
A = 1/2bh
A = 1/2(x)(x/2) = x²/4
36 = x²/4 . . . . . use the given value for area
144 = x² . . . . . . multiply by 4
√144 = 12 = x . . . . . take the square root
The length of leg XY is 12 cm.
360° = 2π
2 = 360° / π
1 rad = 360° / 2π
Wait is it not at all 14.5 or 14 1/2 Because with the math I did I got 14 1/2
