The answer to number 23 is D, 49.
A. opp/adj because the the tangent is the hypotenuse so it eliminates all equations that require the hypotenuse.
A^2+b^2=c^2
a^2+9^2=15^2
a^2+81=225
-81 -81
a^2= 144 (square root both sides)
a=12
Step-by-step explanation:
Area =144m
2
Length =16m
Breadth=
16
144
=9m
Perimeter =2(l+b)
=2(16+9)
=2(25)=50m
Cost =6×50=300Rs.
