Given: klmn is a parallelogram

m∠n=3m∠k,

lf

⊥

kn

,

ld

⊥

nm

kf=2 cm, fn=4 cm

find: lf, ld

how to solve it

The value of LF is 2 cm and LD is 4.24 cm.

Step-by-step explanation:

Given :Parallelogram KLMN

LF  ⊥  KN

LD ⊥  NM

KF = 2 cm, FN = 4 cm

∠N = 3∠K

To find : LF , LD

Solution :

Sum of all angles of parallelogram is 360°.

∠N + ∠K +∠L + ∠M = 360°

∠N + ∠K +∠N + ∠K = 360° (opposites angles are equal in ||gram)

∠3K + ∠K +∠3K + ∠K = 360°

8∠K=360°

∠K = 45°

In triangle KLF

LF = 2 cm

In triangle LMD

LM = KN = 6 cm (Opposites sides are equal in ||gram)

LD = 4.24 cm (approx)

The value of LF is 2 cm and LD is 4.24 cm.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

50- 250 is correct i did that one too
