We have that
cos A=0.25
so
A=arc cos (0.25)-------> using a calculator----> A=75.5225°
Round to the nearest hundredth-----> A=75.52²

the answer is
the option 75.52°

Answer:

Question 10.

Length of the side of the square = $\sqrt{441} = 21$

By Pythagoras' Theorem,

Hypotenuse = $\sqrt{21^{2} + 20^{2} }$ (H > 0)

= 29 m

Ans: 29 m

Question 11.

By Pythagoras' Theorem,

Length of longer side of 42 km = 42- $\sqrt{18^{2} - 15^{2} }$ (L > 0)

= 32.050 km (5 s.f.)

By Pythagoras' Theorem,

Length of the unknown side = $\sqrt{32.050^{2} + 15^{2} }$ (L > 0)

= 35.4 km (3 s.f.)

Ans: 35 km
