Answer:
a) cosθ = 
Step-by-step explanation:
<u><em> Step(i):</em></u>-
Given point ( x , y ) = ( - 2 , 3 )
We know that the polar co-ordinates
x = r cos θ and y = r sinθ
where 
<u><em>Step(ii)</em></u>:-
x = r cos θ
cosθ 
cosθ = 
cosθ =
Answer:
x=155
Step-by-step explanation:
I hope the pictures are clear and you get the concept!
Bisects means to separate in equal parts, meaning each part is equal. This means the equations on each side of the line are equal. Once you equate them, you combine like terms finding your answer.
1) 2x+ 3=x+7
-x -x
x+3 = 7
-3 -3
Answer: x=4 (do this for the others)
2) x=7/2
3) x=5/2
the answer should be 49mm
28*7 / 4 = 49
Absolute value is the distance between a point and 0. Absolute value is always positive. When you're writing numbers in absolute value, make sure you add:
| |
The absolute value of a negative number is also positive. For example:
| -7 | = 7 ⇒The absolute value of -7 is 7.
