Answer:
<em>JM = 5 mm </em>
Step-by-step explanation:
Δ JMK is the right angled triangle ⇒ JM² = JK² + KM²
JM² = 3² + 4²
<em>JM = 5 mm</em>
Answer:
<em>B) x = 3</em>
Step-by-step explanation:
lets plug in the first option to see if it works
3x=9
3*27=9
<em>thats not right</em> ( 3*27 = 81 )
Next, we try the second option
3x=9
3*3=9
<em>that looks more like a resonable answer right?</em>
<em>now to check our work</em>
3+3+3=9
<em>Its correct!</em>

<em>Hope that helps</em>

This is the concept of linear proportionality;
We are required to find the height of the tower in feet. The height of the tower will be found as follows;
[height of tower]/[length of the shadow of tower]=[height of post]/[length of shadow of the post]
height of the tower =h
height of the shadow=100ft
height of post=4 ft 6in=4 1/2 ft= 9/2 ft
length of the post's shadow=3 ft 4 in 3 1/3 ft=10/3 ft
N/B 1 ft= 12 inches
thus;
h/100=(9/2)/(10/3)
multiplying both sides by 100 we get:
h=(9/2)/(10/3)*100
h=9/2*3/10*100
h=135 ft
the answer is 135 ft
