Answer:
x = 21.52
Step-by-step explanation:
Given:
hypotenuse (That has to be found out)
Side adjacent to the given angle
and an angle,
Hence we can say that Cos ratio would be used;
Cos(28) = 19 / x
x = 19 / Cos(28)
x = 21.52
Hope this helps!

</span><span>☛ We know that (-1,-3) is the vertex.
</span>☛ Set up the parabola as y = k(x+1)²-3
☛ 1 = k(0+1)²-3
☛ k = 4
☛ y = 4(x+1)²-3 is the equation

Answer:
1.2 units
Step-by-step explanation:
2.6(d + 1.4) - 2.3d = 4
2.6d + 3.64 - 2.3d = 4
0.3d + 3.64 = 4
0.3d = 0.36
d = 1.2
