An observer on the ground is x meters from the base of the launch pad of a rocket, which is at the same level as the observer. A
few seconds after the rocket takes off vertically, the observer sees its tip at an angle of q° from the horizontal. How far above the ground is the tip of the rocket at that instant? Assume that the ground is level.

Answer: Cylinder uses less material to make.
Box holds more soup then cylinder.
Step-by-step explanation:
Total surface area of cuboidal box =2(lw+wh+lh), l= length, w=width, h=height
Total surface area of cylinder = where r= radius and h is height.
Given , Dimension of box : 7.5 cm by 4.7 cm by 14.5 cm
Dimension of cylinder : radius of 3.3 cm and a height of 10 cm.
Total surface area of box =2((7.5)(4.7)+(4.7)(14.5)+(7.5)(147.5)) sq. cm
= 2(1209.65)
=2419.3 sq. cm
Total surface area of cylinder =
<em>[π=3.14]</em>
(Total surface area of cylinder)<(Total surface area of box )
So, cylinder uses less material to make.
Volume of box = l x w x h
= (7.5)(4.7)(14.5) = 511.13 cubic cm
Volume of cylinder =
= 341.946 cubic cm
As (Volume of box) > (Volume of cylinder )
So, Box holds more soup then cylinder.
Answer:
Option C. x = 5
Step-by-step explanation:
To solve this question we should always keep these two points in our mind.
1). In-center of a triangle is formed by the intersection of the angle bisectors of all interior angles of the triangle.
2). In-center of a triangle is equidistant from all three sides of the triangle.
From the figure attached,
In ΔSRT,
∠ASZ ≅ ∠ZSB [ SZ is an angle bisector of angle ASB]
5x - 9 = 16 [ given in the question]
5x = 16 + 9
5x = 25
x =
x = 5
Therefore, Option C. is the answer.
