Answer:
cosine rule - cos = 
Step-by-step explanation:
Here the ladder is acting as hypotenuse and base as adjacent.
Formula: cosθ = 
The factored form of the expression 10x² -x - 2 is (5x+2)(2x-1)
<h3>Factorizing quadratic equations</h3>
Factorization is a way of simplify. Given the equation 10x² -x - 2
Factorize the given expression
10x² -x - 2
Separate the middle term into -5x and 4x to have;
10x² - 5x + 4x - 2
Factor out the GCF
5x(2x-1)+2(2x-1)
Hence the factored form will be;
(5x+2)(2x-1)
The factored form of the expression 10x² -x - 2 is (5x+2)(2x-1)
