Answer:
x m tall 10 m tall
--------------- = ------------
140 m shadow 4 m shadow
The height of the Stratosphere Tower is 350 m
Step-by-step explanation:
We can use proportions to solve this problem. Put the height of the object over the length of the shadow.
x m tall 10 m tall
--------------- = ------------
140 m shadow 4 m shadow
Using cross products
x*4 = 10 * 140
4x =1400
Divide by 4
4x/4 = 1400/4
x =350
The height of the Stratosphere Tower is 350 m
The expression that must be true for a to be parallel to b are mAngle2 = 58Degrees and <1 = 4x - 10
<h3>Lines and angles</h3>
A line is the shortest distance between two points and the point where two lines meet is known as an angle
From the figure shown
m<2 = 58 degrees (alternate exterior angle)
Since the sum of angles on a straight line is 180 degrees, hence;
3x-1+<2 + 4x - 10= 180
3x-1 + 58 + 4x - 10 =180
7x + 47 = 180
7x = 180- 47
7x = 133
x = 19
Hence the expression that must be true for a to be parallel to b are mAngle2 = 58Degrees and <1 = 4x - 10
