Need help rn 30 points

Ilia_Sergeevich [38]

Answer: X = ( $-\frac{5}{4}\\$ , 6)

Step-by-step explanation:

x(4x - 19) = 30

4x^2 - 19x = 30

4x^2 - 19x - 30 = 0

ax^2 + bx + c = 0

$X{1}=$ $\frac{-b+\sqrt{b^{2} -4ac}}{2a}\\$ = $\frac{19+\sqrt{(-19)^{2} -4(4)(-30)}}{2(4)}\\$ = 6

$X{2}=$ $\frac{-b-\sqrt{b^{2} -4ac}}{2a}\\$ = $\frac{19-\sqrt{(-19)^{2} -4(4)(-30)}}{2(4)}\\$ = $-\frac{5}{4}$ = -1.25

X = ( $-\frac{5}{4}\\$ , 6)

How to solve this problem

S_A_V [24]

Step One
Solve for y
Cos(A) = adjacent / hypotenuse
Cos(A) = y / 8
y = 8 * cos(A)
y = 8 * cos(73)
y = 8 * 0.2924
y = 2.339

Step Two
Solve for x
Sin(A) = opposite / hypotenuse
Sin(73) = x / 8
x = 8 * sin(73)
x = 8 * 0.9563
x = 7.550

Check
x^2 + y^2 =? 8^2
2.339^2 + 7.55^2 =? 8^2
5.471 + 58.53 =? 64
64.000921 = 64 which is close enough.
