Complementary angles sum to 90°
the complement of 64° = 90° - 64° = 26°
the answer is right. its 56
Answer:
Step-by-step explanation:
Given the quadratic equation as:
Let us put 
for simplicity of the equation:
Now, the equation becomes:
Now, let us try to solve the quadratic equation:
So, the solution to the given trigonometric quadratic equation is:
and
Let us try to find the values of 
in the interval 
.
can have a value equal to 
in 1st and 2nd quadrant.
So, can be
For ,
So, the answer is:
Skew lines are lines that are not parallel and do not intersect. The answer cannot be the last two choices because line BD will intersect with GC. The answer has to be the first choice because in the second choice, EA is prallel to GC.
The sales tax rate of an item that costs $4 is 8%
<h2>
Explanation:</h2>
- An item costs $4 before tax
- The same item costs $4.32 after sales tax.
So the tax rate can be calculated as:
Tax rate = $4.32 - $4 = $0.32
Next, you must divide the tax rate by the original price in order to get the sales tax rate:
Sales tax rate = $0.32/4$ = 0.08
In percentage:
Sales tax rate % = 0.08x100% = 8%
