Answer:
A
Step-by-step explanation:
Draw an angle of 15° like this (∠) on a piece of paper, label this angle J, extend the base of the triangle and label the hypotenous 11cm (JK). Do you get the solution now? If no, here is an explanation.
This problem can be explained with sin law,
[Assume KL = 4cm]
(sin15)/4 = (sinL)/11
L = 45.4° or 135° (3 sig. fig.)
Since we got 2 possible case for the angle L, there are two possible set of triangles. Hope this will help you understand more about the problem, comment below if you still have any questions.
The answer would be 15.7142857143
You can get the answer by calculating (5/7) × 22

Answer:
B) vector of the form (2,r, (2-5r)/4)
Step-by-step explanation:
(2,b,c) is orthogonal to (1,-5,-4) if
2*1-5b-4c=0, i.e,
5b+4c=2
We have equation with two variables, so we know that we wil have infinity lot solutions.
Let’s b be some real number r, so we have:
4c=2-5r, i.e,
c=(2-5r)/4.
So there is infinite lot of othogonal vectors of the form: (2, r, (2-5r)/c)) where r is any real number.
