Answer:
Option 1 is correct.
Step-by-step explanation:
Given If the cos 90° = 0, then the value of sin 0° is
As cos Ф=sin(90-Ф)
because angles are complementary i.e Ф+(90-Ф)=90
∴ cos 90° = sin(90-90)°=sin 0°
cos 90°=0 gives sin 0°=0 as cos 90°=sin 0°
because the angles are complementary i.e 90°+0°=90°
Hence, option 1 is correct
Answer: 25.2 in.
just took the test on edg
116.1
If you round each decimal to the nearest tenth it would be 26.7 + 89.4 because you round up if it is 6 and above and round down for 5 and below. The rest is just simple addition.
X/11>=16
X>=16x11
X>=176
