You can round it if needed
Answer:
Step-by-step explanation:
If angle C is the right angle, then side c is the hypotenuse.
Use Pythagoras' Theorem 
to find the length of side a:
Given:
<u>Tan Trig Ratio</u>
where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
Given:
- = A
- O = side opposite angle A = a = 9
- A = side adjacent angle A = b = 2√22
The formula for the light bend would be n1*sin i= n2 * sin r
If you use "sin (90-x)= cos x" principle, you can change the sin in the equation into
n1*sin i= n2 * sin r
n1 * cos a= n2 * cos b
n2/n1= cos a/ cos b
Assuming the n constant is the ratio of the glass compared to water then the answer would be: cos a/ cos b
Answer:
You have the right answer
Step-by-step explanation
Answer:
180 cm2
Area of a polyhedron:
15(=base)x12(=height)
=180cm2
btw parallelogram is a 2D pic how you can come out a ''base'' and ''height''? It should be called a polyhedron. Your question is weird.
If so, your ''area of parallelogram'' is 15cm2 since your question is hecking weird.
Btw it's 15cm2 not 15
Please check ur question b4 u ask
