Fundamentally you can get there using the identity
... sin(a)² + cos(a)² = 1
... 1/cosec(a)² + 1/k² = 1 . . . . . substituting for sec(a) and sin(a)
... 1/cosec(a)² = 1 - 1/k² = (k² -1)/k² . . . . subtract 1/k²
... cosec(a)² = k²/(k² -1) . . . . . Multiply by cosec(a)²k²/(k²-1)
... cosec(a) = k/√(k²-1) . . . . . .take the square root
_____
You can get there slightly faster using the identities tan²=sec²-1; csc=sec/tan.
Answer:
6 and 5
Step-by-step explanation:
Consecutive means that it is continuous, and since the triangle largest side (7) has to be less than the additive of two other sides. Therefore 6 and 5. Hope this helps.
Answer:
Algebra tiles make solving equations, merging like words, or factoring polynomials a visual operation, similar to students using counters to make sense of addition in elementary school, or students using number lines to make sense of integers.

Hey there!!
Let's take the original price of the laptop as $x
Savings you get = $200
This save of $200 is 25% of the original price
If we have have this into an equation..
( 25% ) ( x ) = 200
25% = 25 percent
this would become 25 / 100
Remember =
Per cent = 100
1 dollar = 100 cents , like wise , cent = 100
Moving back on,
( 25 / 100 ) ( x ) = 200
Simplifying 25 / 200
= 1 / 4
( 1 / 4 ) ( x ) = 200
x / 4 = 200
Multiplying by 4 on both sides
x = 800
The original cost = $800
Hope my answer helps!
