Answer:
11,622
Step-by-step explanation:
39 × 298 = 11,622
Have a good day!
Step-by-step explanation:
A1=8
A2=A1+5 plug 8 into A1 here. After getting the value, put into next equation. And repeat until you get A5
A3=A2+5
A4=A3+5
A5=A4+5
Answer: sin
= ±
Step-by-step explanation:
We very well know that,
cos2A=1−2sin²A
⟹ sinA = ±
As required, set A =
& cos a=
,thus we get
sin
=±
∴ sin
=±
= ±
since ,360° <
<450°
,180° <
<225°
Now, we are to select the value with the correct sign. It's is obvious from the above constraints that the angle a/2 lies in the III-quadrant where 'sine' has negative value, thus the required value is negative.
hope it helped!
Answer:
x = 30°
Step-by-step explanation:
We know that the sum of all of the interior angles of a triangle is 180°, therefore, we can write the following equation:
x + 2x + 3x = 180
6x = 180
x = 30°
Y = ln |1 + t - t^3| = (1 - 3t^2)/(1 + t - t^3)
