Find on x on this triangle

correct answer is B.

Step-by-step explanation:

in the small triangle

taking 60 as reference angle

b =

so

tan 60 = p/b

= p/()

30 = p

so

(taking 45 as reference angle)

so

in bigger triangle

b = 20

so

tan 45 = p/b

1 = p/(20)

p = 20

so h^2 = p^2 + b^2

so

h^2 = (20)^2 +( 20)^2

= 1200 + 1200

h^2 = 2400

h =

=20

so x = 20

d

step-by-step explanation:

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
