I can't see the photo!????????
A, h, and b are collinear
Answer:
134°
Step-by-step explanation:
The sum of interior angles of a regular polygon is: (n - 2)180
Hexagon has six sides, n is 6
Sum of it's angles is (6 - 2)180 = 720
sum of our hexagon:
119 + 129 + 104 + 139 + 95 + x = 720°
x is 134°
Answer:
see explanation
Step-by-step explanation:
Using De Moivre's theorem
Given
[ 4(cos15° + isin15° ) ]³, then
= 4³ [ cos(3 × 15°) + isin(3 × 15°) ]
= 64 (cos45° + isin45° )
= 64 ( + i )
= 64 ( (1 + i) )
= 32 (1 + i)
= 32 + 32 i
Answer:
C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° = , cos45° = , thus
sin60° = = = ( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp =
Now consider the right triangle on the right, using the cosine ratio
cos45° = = = ( cross- multiply )
x = × = → C
