You use Pythagorean theorem...a^2+b^2=c^2
a=12ft
b=47-31.. height of the triangle
c=distance between two roof tops
(12)^2+(16)^2=c^2
144+256=c^2
400=c^2, take square root of both sides
c=20ft
25/100=30/x x=120 (30+70y)/(120+100y)=50/100 100y=?
Answer:
$8/pound
Step-by-step explanation:
$40 ÷ 5 lbs = 8$ per pound
If we assume the triangles are similar, then
.. 15/10 = x/8
.. x = 8*(15/10) = 12
Answer:
9.8 degree + 80.2 degree
As both need to add up to 90 degree to be complementary.
Step-by-step explanation:
Complementary angle means adds up to 90 degree.
Therefore- 90-80.2 = 9.8 degree
