Answer:
fdg=gce ( vertically opposite angle)
or,fdg=23
Step-by-step explanation:
or, x+fdg = 90 (supplementary angle)
or,x+23=90
or, x =90-23
or,x=67
so, the value of x is 23

Answer:
(a) 10 seconds
(b) 490 meters
Step-by-step explanation:
<h2>
<u>(</u><u>A</u><u>)</u></h2>
When the object hits the ground, it shows that the height is 0. Hence, h(t) = 0.
0 = 4.9(10+t)(10-t)
0 = (10+t)(10-t)
t = 10, -10
Since time cannot be negative, t = -10 will be rejected.
Therefore, t = 10 seconds
<h2>
<u>(</u><u>B)</u></h2>
Based on the question, <em>"</em><em>t </em><em>seconds </em><em>after </em><em>the </em><em>object </em><em>is </em><em>dropped </em><em>from </em><em>a </em><em>helicopter"</em><em>,</em><em> </em>means that the time starts right after the object is dropped from the helicopter, this shows that t = 0.
h(0) = 4.9(10+0)(10-0)
= 4.9(100)
= 490 meters
