Answer:

$5\sqrt{7}$

Step-by-step explanation:

$\frac{30\sqrt{14} }{6\sqrt{2} }$

Cancel out 6 in both numerator and denominator.

$\frac{5\sqrt{14} }{\sqrt{2} }$ Rationalize the denominator of $\frac{5\sqrt{14} }{\sqrt{2} }$ by multiplying the numerator and denominator by $\sqrt{2}$ .

$\frac{5\sqrt{14}\sqrt{2} }{(\sqrt{2})^{2} }$

The square of $\sqrt{2}$ is 2

Factor 14=2 × 7. Rewrite the square root of the product $\sqrt{2x7}$ as the product of square roots $\sqrt{2}\sqrt{7}$ .

$\frac{5\sqrt{2}\sqrt{7}\sqrt{2} }{2}$

Multiply $\sqrt{2}$ and $\sqrt{2}$ to get 2.

$\frac{5x2\sqrt{7} }{2}$

Cancel out 2 and 2.

$5\sqrt{7}$

Hope it helps and have a great day! =D

Answer:

Angle 1 - 51

Angle 2 - 39

Angle 3 - 90

Angle 4 - 51

Angle 5 - 17

Angle 6 - 129

Step-by-step explanation:

Angle 1 = 180 - 90 - 39 = 51

Angle 2 = 90 - Angle 2 (51) = 39

Angle 3 = 90

Angle 4 = 180 - Angle 2 (39) - Angle 3 (90) = 51

Angle 5 = 180- 90 - 34 -39 = 17

Angle 6 = 180 - Angle 4 (51) = 129
