Answer:
62.2%
Step-by-step explanation:
We are told in the question that:
The total number of students going = 45 students
The number of year 8 students going for the ski trip = 28 students
The proportion is :
28/45
Converting this proportion to a percentage.
28/45 × 100
= 0.6222222222222222 × 100
62.222222222%
Approximately to 1 decimal place is
62.2%
Answer:
2 1/16
Step-by-step explanation:
(1/4)^2 + 2 = 1/16 + 2 = 33/16 = 2 1/16
Answer:
75
Step-by-step explanation:
x is the exterior angle of triangle BDH, meaning that the if you add up the other two angles of triangle BDH, which are the opposite interior angles of angle x, you will get x, which is 75.
If you want to visualize the exterior angle theory, you can look at an example in the picture in this post.
Hope this answer helps you, and was deserving of a Brainiest answer. :)

Answer:
Here,
(cosθ + sinθ/sinθ) – (cosθ – sinθ/cosθ) = secθ cscθ
Now, Cross Multiplication
(cosθ + sinθ/sinθ) – (cosθ – sinθ/cosθ) = secθ cscθ
cosθ(cosθ + sinθ) – sinθ(cosθ – sinθ)/sinθ cosθ
cos²θ + sinθ cosθ – sinθ cosθ + sin²θ/sinθ cosθ
cos²θ + sin²θ/sinθ cosθ
Here, we know the identity
cos²θ + sin²θ = 1
So,
cos²θ + sin²θ/sinθ cosθ can be written as
1/sinθ cosθ
Here, we also know the identity
1/sinθ = cscθ
1/cosθ = secθ
1/sinθ cosθ can be written as
secθ cscθ
= L.H.S
Hence Proved!!
