Pythagoras theorem only works for right triangle (90 degree)
Trigonometry (sin, cos, tan) works everywhere!
Hopefully I answered your question!

It is negative six because down three is -3 so 3+3 =6 but the numbers are negative so the answer is -6
Answer:
75 degrees, we know that already so look below lol.
Step-by-step explanation:
This triangle is an isosceles triangle, LP is equivalent to LQ, and angles LQP and LPQ are also equivalent. We understand that PLQ is equal to 30 degrees, since its complementary to triangle LQM.
180 - 30 = 150
150/2 = 75.

(-9, -1)
(-9,-1) . -1 because that is the y intercept from the equation.
-9 because when you substitute -2 for x, and multiply by 4, you get -8. Then you subtract one, making the x value -9.
Therefore, the ordered pair of the solution is (-9,-1)
Hope this helps, please consider marking branliest if it did.
. However, there is a problem. The questions aren't actually possible without using sine, cosine, and tangent (which are mathematical ratios if you didn't know). I can help you with this but it will take time explaining.
