Answer:
11.28m
Step-by-step explanation:
The computation of the height of the spire is shown below:
let us assume the height of the spire be x
Now
For triangle ABD
Tan 43 degrees = h ÷ x
x = h × cot 43 degrees
= 1.07236 h
For triangle ABC
tan 15 degrees = h ÷ (30 + x)
0.2679 = h ÷ 30 + 1.07236h
8.038 + 0.28728 h = h
h = 11.28m
$4.07 × 9.6= $39.072 or $39.07; $20 × 2= $40; 40 - 39.07= 0.93.
The answer is $0.93.

5.5(7.5 + x)
Multiply 7.5 and x by 5.5.
41.25 + 5.5x
41.25 is the area of the blue part of the mural, and 5.5x is the area of the red part of the mural.
2x+4y=16
2x+4(4)=16
2x+16=16
-16=-16=2x=0
