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

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
