So firstly, multiply both sides by 4 (the reciprocal of 1/4):
Next, subtract both sides by 2 and your answer will be:
tan x = opp/hyp
x is the side of the building and 6 is the distance from the bottom of the ladder to the building
tan 13 = 6/x
multiply both sides by x
x tan 13 =6
divide both sides by tan 13
x = 6/ tan 13
x = 26
The ladder goes 26 ft up the building
Answer:
Step-by-step explanation:
The area of the trapezoid is given by a=1/2(a+b)h
where a=8.52cm , b=22.2cm and h=9.86cm
The answer is 19.125 or you can round it to 19.13
