Answer:
Step-by-step explanation:
6(5+13x)-13(1-x)
30+78x-13+13x
30-13+78x+13x
17+91x
i think it is the answer
The measure of T, rounded to the nearest degree is 22
This is a isosceles triangle. all sides degrees added together (triangle) is equal to 180.
we know one side is 55°, and since its isosceles, it will be congruent on both sides. so there are 2 55°.
since the sum of all angles is 180°, the equation will be 55°+55°+x=180
combine like terms (55+55), which equals to 110.
last, 180-110 = 70
so the answer will be x = 70°
Answer:
third option
Step-by-step explanation:
Using De Moivre's theorem
( + i)³ , then
| + i |
=
= = = 2
arg( + i) = ( ) =
Thus
( + i)³
= 2³ [ cos(3 × ) + isin( 3 × ) ]
= 8 [ cos() + isin( ) ]
Here is a picture of my work. The range is solved when you subtract the biggest number from the smallest number. Hope this helps
