Help! What is the measure of angle K in the triangle below?

Mathematics

ANSWER

K=43° to the nearest degree

EXPLANATION

Use the sine rule:

\frac{ \sin(J) }{j}  =  \frac{ \sin(L)}{l}

Substitute the values

\frac{ \sin(J) }{10}  =  \frac{ \sin(102 \degree)}{17}

This gives us,

\sin(J)   =  \frac{ \sin(102 \degree)}{17}  \times 10

J =  \sin ^{ - 1} (0.57538094161) = 35.126 \degree

J is approximately 35°

We now use the sum of interior angles of a triangle to find K.

K + 35 \degree + 102 \degree = 180 \degree

K  = 180 \degree -  35 \degree  -  102 \degree

K  = 43 \degree

Please help! I have no idea how to do this.

11.  y=-1/3x-4

Plug the slope into m in y=mx+b and  then plug in your point and solve for b. You get C

12.  Parallel means it has the same slope or the same m, so the -1/2 stays the same and you plug that and your point into the y=mx+b and solve for b again. You get D, y=-1/2x-9

13.   Perpendicular means that the slope is the opposite reciprocal so you flip it and multiply it by -1. You then plug that in for your slope and plug in your points and you get A, y=9x+13

Please answer/do 3-7!! Whoever does it right, i will give brainlest! :) also, PLEASE FILL IT OUT EITHER ON PAPER/ PHONE etc. !!!
meriva

Answer:

3-7 is negitive 4 in your answer it's 3-7 = -4

Step-by-step explanation:

It's negitive four because if you subtract you will get 4 but since it's other way around. And if you do It, it will say that even if there is no negitive sign it won't change the problem because it's still the same problem.

1) 3 - 7

2) there are 3 ways to do this to get the answer:

1) 3/7

2) 7 + 3 - 4 + 3

3) now 7 + 3 is ten - 7 is 3 + 4 is 7, so then if you do 3 - 7 you get negitive four

4) now check your answer by subtracting 3 and 7

5) then you get -4

btw: ( hope this helped :) )
