Answer:
After finding like terms and solving, we get 
Step-by-step explanation:
We need to find like terms and simplify the expression 
Like terms: The terms who have same variable and exponent are called like terms.
So, Combining like terms and solving:

So, after finding like terms and solving, we get 
<u><em>Note: In the question given we have - and + sign with the term 5x</em></u> i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2
I have solved using +5x, but if the term is -5x then the solution will be:

So, the answer will be: 
Answer:
The correct answer is option 1
23.96°
Step-by-step explanation:
Tan ∅ = Opposite side/Adjacent side
From the given figure we can see that it is a right angled triangle.
<u>To find the value of x
</u>
Tan ∅ = Opposite side/Adjacent side
Opposite side = 4
Adjacent side = 9
Tan x = 4/9 = 0.4444
x = tan⁻¹ (0.4444) = 23.9624 ≈ 23.96°
Therefore the correct answer is first option.
23.96°
