Answer:
<u><em>The value of x is 2.6</em></u>
Step-by-step explanation:
<em>Use pythagorean theorem</em>
a^2+b^2=c^2
<em>Then substitute</em>
1^2+2.4^2=c^2
<em>Then evaluate</em>
1+5.76=c^2
<em>Add</em>
c^2=6.76
<em>Isolate c by finding the sqrt of 6.76</em>
c=2.6
3/4 is equal to .75 .................................
542(1+1/4)
542(4/4+1/4)
542(5/4)
677.5
