1) a
The building is 4*15 = 60 feet = 720 inches high. The ratio is 720/5 = 144 

2) b 
The ratio is 9/(1/4) = 36. So 1 foot = 12 inches and 12/36 = 1/3 

3) c 
With a ratio of 1:72, a 7.5 inch wingspan represents 7.5*72 = 45 feet 

I hope this helps!

Step-by-step explanation:

Hey There!

So these triangles are congruent so segment CD is equal to segment DB

so to find x we use the equation

7x+10=10x+7

now we solve for x

step 1 subtract each side by 7

10-7=3

7-7 cancels out

now we have 7x+3=10x

step 2 subtract each side by 7 x

10x-7x=3x

7x-7x= cancels out

now we have

3x=3

step 3 divide each side by 3

3/3=1

3/3 cancels out

now we have

x=1
