Answer:
A/12.5=h
Step-by-step explanation:
A is 12.5 x h so you do inverse to work out height
Y=3x+12 (its the first option)
I did the assignment.

tanB + cotB = (sinB)/(cosB) + (cosB)/(sinB)
= (sin2B + cos2B)/[(cosB)(sinB)]
= 1/[(cosB)(sinB)]
= (1/cosB)(1/sinB)
= (secB)(cscB)
a= 92(18) =1656
Area= 1656m
p= 2(92+18) =220
Perimeter= 220m
