6 ×11=66+6×11=66+2×11=22 add all the totals is 154 wich the answer
Answer:
6). Option A
7). Option C
8). Y = 62°
Step-by-step explanation:
6). Let the missing angle = x°
By applying cosine rule to find the missing angle,
cos(x°) = 
= 
x = 
x = 18.92°
x ≈ 19°
Option A is the answer.
7). Let the missing angle = x°
By applying cosine rule in the given triangle,
cos(x°) = 
cos(x°) = 
x = 
x = 13.17
x = 13°
Therefore, Option C is the answer.
8). tanY = 1.8807
Y = 
Y = 62°
#2 Is Complementary because angle 1 and 2 are equal to 90 degrees
#4 Is Adjacent. That mean front he middle point/vertex both angles are on the same side and don’t over lap.
To finish the rest i have some notes.
The standard form of a parabola is

, where h and k are the coordinates of the vertex and the a is the value that either compresses it vertically or draws it out horizontally (aka stretched). The h value also indicates side to side movement, while the k value indicates up or down movement. The larger the a value, the closer the parabola "hugs" the axis of symmetry. All in all here, we have a parabola in g(x) that is vertically compressed and is moving down from its original vertex of f(x) which (0, 0) by 2 units. Therefore, our choice is b.
