Given δfgh ~ δlmn, which must be true? select all that apply.
a. fglm=fhln
b. fh ~ ln
c. m∠fm∠l=m∠gm∠m
d. gh≅mn
e. m∠h≅m∠n

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

b, 20 yards
