<span>Using the rule of 3, 60x100% =6000(obviously) and 6000/75 = 80</span>
Answer:
<em> 50° </em>
Step-by-step explanation:
x° = 180° - (102° + 28°) =<em> 50°</em>
Step-by-step explanation:
Shortest way to solve this question is to find the factors of the given expression.
The given expression is (x² + 13).
Now we have to factorize it.
(x² + 13) = x² + (√13)²
= x² + [-(i)²√(13)²] [Since i = √(-1)]
= x² - (i√13)²
= (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]-by-
I think this is the answer. if not sorry
