Answer: 90/pi degrees

Step-by-step explanation:

It forms a 15cm arc from a circle of radius 30 cm.

The diameter is 30*2*pi = 60pi cm. So the arc is 15/60pi = 1/4pi of the way around a 360 degree circle. This is 1/4pi * 360 = 90/pi degrees.

Hope that helped,

Answer:

$\huge \boxed{2\sqrt{5} +\sqrt{35}}$

Step-by-step explanation:

$\sqrt{5} (2+\sqrt{7} )$

Expand brackets.

$\sqrt{5} (2)+\sqrt{5}(\sqrt{7} )$

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

Apply radical rule : $\sqrt{a} \sqrt{b} =\sqrt{ab}$

$2\sqrt{5} +\sqrt{5 \times 7}$

$2\sqrt{5} +\sqrt{35}$
