B x h = 8 x 10 = 80. 80 divided by 2 is 40 so 40cm
The answer is .54
54/100=.54
We know that
in the IV quadrant
cos theta is positive
and
sin theta is negative
so
cot theta=cos theta/sin theta--------> cot theta must be negative
sec theta=1/cos theta------> sec theta must be positive
therefore
the answer is the option
<span>A. cannot be true because sec(theta) is greater than zero in quadrant 4</span>
7/12 divided by 14/15 is the same as
7/12 x 15/14
cross cancel and multiply
5/8 is the answer
hope this helps
2a + 3 + a = 180
- 3 - 3
2a + a = 177
3a = 177
---- ---- = 59
3 3
59 is a.
