A 30° – 60° – 90° triangle is shown below. Find the value of x.
1 answer:
Answer:
5
Step-by-step explanation:
In a 30-60-90 triangle, the side opposite the 30 degree angle (x) is equal to n, the side opposite the 60 degree angle (y) is equal to n, and the hypotenuse (10) is equal to 2n
knowing this, set 10 = 2n
n = 5
since we want to find x, the side opposite the 30 degree angle, this is equal to n = 5
x = 5

Answer:
A trinomial of degree 5
Step-by-step explanation:
A monomial has only 1 term
A binomial has 2 terms
A trinomial has 3 terms
4 + 3x³ - 7x ← has 3 terms and is therefore a trinomial
The degree of a polynomial is determined by the largest exponent of the variable in the expression
4 is the term with the largest exponent in the expression
Hence a polynomial of degree 5
