what i said above
Answer:
23) option c
JL ≈ 9.3
25) option c
y ≈ 9.6
Step-by-step explanation:
<h3>25)</h3>
Given in the question that,
cos(21°) = 9 / y
y = 9/cos(21°)
y = 9.64
y ≈ 9.6(nearest tenth)
<h3>23)</h3>
Given in the question that the hypotenuse of right angle triangle = 12
To find,
height of the right angle triangle
angle k = 39°
so by using trigonometry identity
cos(39) = opp/hypo
cos(39) = JL / KL
JL = cos(39)(12)
JL = 9.32
JL ≈ 9.3

The sum of two vectors is the largest when the vectors are pointing in the same direction. The Resultant of two vectors depends on the cosine of the angle between them, and the maximum value of cosine is 1 which means the angle between the vectors should be zero
. So, the sum of the vectors will be largest when both the vectors are in the same direction.
Answer:
When B is 3, it is not answerable. The sides are not equal, if it were -3 the answer would be 16.
