HURRY I NEED HELP!!! Solve triangle JKL round to the answer to the nearest tenth
creativ13 [48]

Answer:

It's Option A.

Step-by-step explanation:

Using the Cosine Rule:

cos < K =  (3.9^2 - 1.9^2 - 2.8^2) / (-2 *1.9*2.8)

=  3.76 / -10.64

= - 0.3534.

m < K = 110.7 degrees.

Using the Sine Rule:

3.9 / sin 110.7 = 2.8 / sin <J

sin J =   2.8 sin 110.7/ 3.9 = 0.6716

m < J = 42.2 degrees

So m < L = 180 - (110.7 + 42.2)

= 180 - 152.9

= 27.1 degrees

Question 1: Verify that parallelogram ABCD with vertices A(-5,-1), B(-9,6), C(-1,5), and D(3,-2) is a rhombus by showing that it
kotegsom [21]
The first one can be proven by graphing the parallelogram and the diagonals.

The measure of angle 2 is 160 because it is a vertical angle to angle 1. The measure of angle 3 is 10 because the two other angles must each be 10 in order for the sum of all three angles to equal 180 for the triangles.

I have no idea for the third one however.

Hope this helps!
