Answer:
28
Step-by-step explanation:
The interior triangle has a right angle, and one of its corners is 62, so the other angle, which is vertical to x, is 180-(90+62)=28, so x=28.
Step-by-step explanation:
<u>sin90</u> = <u>sinx</u>
19 17
sin x=0.8947
x=63.47°
Answer:
The mode would not change
Step-by-step explanation:
Mode is the frequency of 1 number. In this case, the mode is 3. If we add 8, the frequency of 3 would not change; there would still be 4 3's, and 3 would still have the most of itself.
The equation for the given parabola is; x = ¹/₁₂(y - 3)² - 2

</h3><h3>How to find the equation of a parabola?</h3>
From the graph, we see that;
Focus = (1, 3)
Directrix; x = -5
General form of equation of a parabola is;
(y - k)² = 4p(x - h)
where;
focus is (h + p, k)
directrix is x = h - p
Thus;
(1, 3) = (h + p, k)
h + p = 1 -----(1)
k = 3
Similarly;
h - p = -5 -----(2)
Add eq 1 to eq 2 to get;
2h = -4
h = -2
-2 - p = -5
p = 3
Thus, equation of the parabola is;
(y - 3)² = 4(3)(x - (-2))
(y - 3)² = 12(x + 2)
divide both sides by 12 to get;
¹/₁₂(y - 3)² = x + 2
x = ¹/₁₂(y - 3)² - 2
