Answer:
1.
Step-by-step explanation:
sec 16° cosec 74° - cot 74° tan 16°
= 1/ cos 16 * 1/ sin 74 - 1/tan 74 * tan16
= 1/ cos16 sin 74 - cos74/ sin74 * sin 16 / cos 16
Now cos 16 = sin 74 and sin 16 = cos 74 (supplementary angles) so:
= 1 / cos^2 16 - sin 16/cos 16 * sin 16 / cos 16
=( 1 - sin ^2 16 )/ cos^2 16
= cos^2 16 / cos^2 16
= 1.
Answer:x=1 y=2
Step-by-step explanation:
you add and get 8x=8 x=1 so plugging in one you get 5+2y=9 so 4=2y so y=2
Answer:
-120 degrees.
Step-by-step explanation:
This triangle has a rotational symmetry of 3 (it repeats its orientation 3 times as it makes a complete circle around the center), so the angle of rotation is 360 / 3 = 120 degrees.
As the rotation is counter clockwise strictly speaking the answer is -120 degrees.
