When there is a multiplication involving exponents, we need to evaluate the numbers and each variables separately. In this case, we have 5 and 4 as the numbers, and w and h for the variables.
When we multiply 5 and 4 we get:
For w, we have
,
,
. While we are multiplying the w's, we need to add the exponents together to get the final answer:
For h's, there are
,
,
. When we apply the same thing to h's, we get
For the final step, we need to write all of these together:
Answer:
65, 90, 30, 24(in order abcd)
Step-by-step explanation:
The sum of all angles in a triangle is 180 degrees, so knowing this, you should be able to get all of them.
1) x+65+50 = 180, so x= 65
2)x+34+56 =180, so x= 90
3)90+3x=180, so x=30
4)90+66+x=180, x=24
A fraction that means the same as 2/3 is 4/6.
To find this, you can simply multiple both the numerator and denominator (top and bottom) by any number as long as it's the same number for both top and bottom.
In this case, we used 2 as the number, and multipled it to the top and bottom of 2/3, to get 4/6.
I hope this helps!
Answer:
I dont understand what u want me to solve tho
Answer:
θ = 36.94°
Step-by-step explanation:
Brewster's law for polarization states that; tan(θ_p) = n2/n1
Where ;
θ_p is the polarizing angle
n1 is the index of refraction of first material
n2 is the index of refraction of second material
Now, our first material here is air while second material is water.
Index of refraction of water = 1.33 while index of refraction of air is 1
Thus,
tan(θ_p) = n2/n1 = 1.33/1
tan(θ_p) = 1.33
(θ_p) = tan^(-1)1.33
(θ_p) = 53.06°
Now, polarizing angle is the angle of incidence for which all the reflected light is polarized and it's above the vertical. Thus to get the angle to the horizontal, it will be;
θ = 90° - (θ_p) = 90° - 53.06° = 36.94°
