In ΔKLM, m = 160 cm, ∠M=145° and ∠K=28°. Find the length of l, to the nearest 10th of a centimeter.
Montano1993 [528]

Answer:

34.0 m

Step-by-step explanation:

The total angle sum in a triangle should be 180° hence the missing angle will be given by

180°-145°-28°=7°

Using sine rule

\frac {m}{sin M}=\frac {l}{sin L}=\frac {k}{sin K}

By substituting 160 for m, 145° for M and 7° for L then

\frac {160}{sin 145^{\circ}}=\frac {l}{sin 7^{\circ}}

Making l the subject then

l=\frac {160 sin 7^{\circ}}{sin 145^{\circ}}=33.9956345990643m\\l\approx 34.0m

Step-by-step explanation:

The figures are the same just flipped. We can tell AD=NM ON=AB, BC=OP. Thus DC =MP

DC has the length of 6 and because MP is congruent to DC it also has 6.

If two triangles have equivalent angle measures then they are congruent
const2013 [10]
If two triangles have equivalent angle measures then they are congruent isn’t enough to prove that the two triangles are congruent. Two triangles are congruent if they have both the same three sides and also with the same three angles however, the given is only specifying in angles therefore, it can’t assure the argument that is the two triangles with the same angle is congruent.

Eli is making guacamole. He uses 2 tablespoons of cilantro for every 3 avacados. At this rate, how many tablespoons of cilantro
weeeeeb [17]
Hello! So we can set this up as a ratio of 2:3. In other words, 2 tablespoons of cilantro for every 3 avocados. To find the amount of cilantro for 9 avocados, you have to think about basic multiplication. 3 * 3 = 9. So then, you should do the same thing to the other part. 2 * 3 = 6. Eli will need 6 tablespoons of cilantro for 9 avocados.
