Use the Pythagorean theorem...
a²+b²=c², in this case a²=c²-b<span>²</span>
a²+24²=33.94113<span>²
a</span><span>²+576=1,152.00031
a</span><span>²=576.000306
a=24 (If you need the exact number, not rounded, it is 24.0000064)</span>
-512.
Type negative 8 to the third power in google. It really is the answer. :)
Answer:
I think its A
Step-by-step explanation:

<h3>area of shaded figure= </h3>
<h2>area of whole rectangle</h2>
= lengthx breadth=15x30= 450 cm²
<h3>area of unshaded region= lengthx breadth= (30-8)x 15cm²= 22x 15cm²= 330cm²</h3>
<h3>are of shaded region</h3>
= area of whole rectangle -area of unshaded region= 450cm²-330cm²= 120cm²
therefore 120 is correct answer
-1(3x-2y=27)
3x-y=24
-3x+2y=-27
+3x-y = 24
y=-3
3x-(-3)=24
3x+3=24
-3. -3
3x=21
/3. /3
X=7
Hope that helps
