Make x the subject of the formula for Q20.

saul85 [17]

Answer:

$x = \sqrt{m(\frac{a}{b})^{2} +n }$

Step-by-step explanation:

$a\sqrt{(\frac{x^{2} - n }{m}) } = \frac{a^{2} }{b}$

$\sqrt{\frac{x^{2} - n }{m} } = \frac{a}{b}$ [Divide both sides by $a$ ]

$\frac{x^{2} - n}{m} = (\frac{a}{b} )^{2}$ [Square both sides]

$x^{2} -n = m(\frac{a}{b} )^{2}$ [Multiply both sides by m]

$x^{2} =m(\frac{a}{b} )^{2} + n$ [Bring n to the right]

$x = \sqrt{m(\frac{a}{b})^{2} +n }$ [Square root both sides]

In a set of three lines, a pair of parallel lines is intersected by a transversal. The intersection forms eight special angles.

My name is Ann [436]

Answer:

Part A: 4x = -5(x-18)

Part B: A and B both = 40 degrees

Step-by-step explanation:

Ok, corresponding angles are in the same position on the two parallel lines cut by the transversal. And they are equal in measure. So, upper right = upper right.

So A = B

4x = -5(x -18)

4x = -5x + 90

9x = 90

x = 10

Angle A = 4x = 40 degrees, which means angle B is also 40, but let's show the work:

Angle B = -5(x - 18) = -50 + 90 = 40
