Answer:
It is equal to 0.
Step-by-step explanation:
I can simplify it as follows:
sinα sin(90 - α) - cos(90 - α)(cosα)
Now sin(90 -α) = cosα and cos(90 - α) = sinα) ( for α < 90)
So the expression becomes:
sinαcosα - sinαcosα
= 0 .
Answer:
are corresponding angles and are congruent to each other.
are alternate exterior angles and thus congruent to each other.
are interior angles on the same side, and they are supplementary(sum=180°).
Step-by-step explanation:
Given:
Line 
Line 
is traversal.
By angle properties we can name the angle relationship of given angle pairs.
are corresponding angles and are congruent to each other.
are alternate exterior angles and thus congruent to each other.
are interior angles on the same side, and thus they are supplementary.
Answer: If the answer needs to be simplified, then the answer would be
-20c^2 d^3 - 16cd^2
Step-by-step explanation:
Answer:
If A is wrong then B I think
Step-by-step explanation:
After 6x+48=72, you have to subtract 48 on both sides not add. Your final answer will be x=4. 72-48=24.. 24/6= 4.
