Answer:
<h2>D. (-2, 4)</h2>
Step-by-step explanation:
Put the coordinates of the points and check the equality.
2x + 3y = 8
A. (1, 4) → x = 1, y = 4
2(1) + 3(4) = 2 + 12 = 14 ≠ 8
B. (2, 2) → x = 2, y = 2
2(2) + 3(2) = 4 + 6 = 10 ≠ 8
C. (-1, 3) → x = -1, y = 3
2(-1) + 3(3) = -2 + 9 = 7 ≠ 8
D. (-2, 4) → x = -2, y = 4
2(-2) + 3(4) = -4 + 12 = 8 CORRECT
Answer:

Step-by-step Explanation:
Angle of depression is congruent to angle of elevation.
Therefore, angle of elevation of the given figure, which is opposite to x is 25°.
Adjacent length = 11 yd
Opposite length = x
Trigonometric ratio formula for finding x is shown below:


Multiply both sides by 11 to solve for x


(to the nearest tenth)
Answer:
x = 30°
Step-by-step explanation:
The arcsin (inverse sine) function can be used. Be sure to set your calculator to degrees mode.
sin(x) = 1/2
arcsin(sin(x)) = arcsin(1/2)
x = arcsin(1/2)
x = 30°
