Answer:
12.5
Step-by-step explanation:
First you times 45 and 25 together, since product means multilpication. 45*25= 1125
Then you add 53 and 73, which is 90. Then you divide, which equals to the sum of 12.5. Hope this helps!
A+10=b5, I am not to sure but try it I am sorry if it is incorrect.

Answer:
<em>17.5 feet</em>
<em></em>
Step-by-step explanation:
<em>since the roof has a 5-12 pitch, this means that the roof rises by 5 units for every 12 unit run.</em>
Height of eaves off the ground is 10 feet
If the eave to eave width of the house is 36 feet, <em>then the distance of one eaves to the center will be 36/2 = 18 feet</em>
since the pitch is 5-12, then the height of the highest point of the roof from the eave will be gotten from the relationship below
=
where y is the height of the highest point of the roof from the eaves
5 x 18 = 12y
90 = 12y
y = 90/12 = 7.5 feet
<em>total height of roof at highest point will be height of the eaves off the ground plus height of highest point of the roof from the eaves</em>
total height of roof = 10 + 7.5 = <em>17.5 feet</em>
