Answer:

- (\frac{15 - 4\sqrt{3} }{11} )

Step-by-step explanation:

\frac{\sqrt{3}-6}{\sqrt{3} +6} = \frac{(\sqrt{3}-6)(\sqrt{3}-6)}{(\sqrt{3} +6)(\sqrt{3} -6)}

= \frac{(\sqrt{3})^2 - (2\times6\times\sqrt{3}) +6^{2}   }{(\sqrt{3})^2 - 6^{2}}  = \frac{9 - 12\sqrt{3} + 36}{3 - 36}

\frac{45 -12\sqrt{3}  }{-33} =- (\frac{15 - 4\sqrt{3} }{11} )

Please help me solve this (ASAP)
joja [24]
Since complementary angles add to 90°, (4x - 1) and (5x + 19), also add to 90°.

Thus, lets form an equation:

90 = 5x + 19 + 4x - 1
72 = 9x
x = 9

Thus, the measure of angle B is 64°.
