The scale for the model length of the fuselage obtained by taking the ratio of the model length and the actual length is 0.125
Actual Length of fuselage = 170 feets
Length of fuselage on model = 21.25
<u>To obtain the scale of the model, we take the ratio of the model length and the actual length</u> :
- Model length / Actual length
- 21.25 feets / 170 feets = 0.125
Therefore, the scale for the model length of the fuselage is 0.125

Answer:
x=44 degrees
Step-by-step explanation:
5y-4 has to equal 81 in order for the two triangles to be congruent.
The sum of the interior angles of a triangle is always 180 degrees.
81+51=132 degrees
180-132=48
x+4=48
x=48-4
x=44 degrees
