Answer:

Step-by-step explanation:

recall law of Sines   Sin(A) /a = Sin(B) / b

for this question

F = A = 105  and a = 37

E = B  and b = 28

then plug those into our law of Sines equations

Sin(105) / 37 = Sin(B) / 28

0.025846 = Sin(B) / 28

28 * 0.025846 = Sin(B)

0.72369 = Sin(B)

arcSin(0.72369) = arcSin ( Sin ( B ) )

46.3599 = B

E = 46°  ( rounded to the nearest degree)

The area of the triangle formed by points of intersection of parabola y=a(x−3)(x+2) with the coordinate axes is 10. Find a if it
ICE Princess25 [194]

Answer: a = 4

Step-by-step explanation: Area of a triangle is calculated as: A_{t}=\frac{b.h}{2}.

The triangle formed by the parabola has base (b) equal to the distance between the points where the graph touches x-axis and height (h) is the point where graph touches the y-axis.

The points on the x-axis are the roots of the quadratic equation:

a(x-3)(x+2)=0

(x-3)(x+2)=0

x - 3 = 0

x = 3

or

x + 2 = 0

x = -2

So, base is the distance between (-2,0) and (3,0).

Since they are in the same coordinate, distance will be:

b = 3 - (-2)

b = 5

Area of the triangle is 10. So constant a is

10=\frac{5.a}{2}

5a = 10.2

a = 4

The constant a of the function y = a(x-3)(x+2) is 4.
