Answer:
154°
Step-by-step explanation:
m<LOM + m<MON = m<LON and since m<LON is a straight angle the measure of it would be 180°
9x - 91 + 6x + 76 = 180 add like terms
15x - 15 = 180
15x = 195
x = 13
m<MON is 6x + 76 replace x with 13 ➡ 6×13 + 76 = 154°
1: answer is 8a+24b
2: answer is 6x+33y

Answer:
Option D
Step-by-step explanation:
Option A
x² - 3x² + 2x² = 0
Therefore, the given polynomial has no roots.
Option B
x² + 2x + 8
By quadratic formula,
x = 
= 
Therefore, roots are imaginary and for a polynomial with degree 1 or more than 1, both the roots can't be imaginary.
So the polynomial can't have exactly two roots.
Option C
99x³ - 33x + 1
Since the polynomial is of degree 3, so it will have three roots.
Therefore, the polynomial will not have exactly 2 roots.
Option D
√2x - 3x² + 7√2
By quadratic formula,
x = 
x = 
There are exactly two real roots.
Therefore Option D is the answer.
Option E
4x + 11x - 111
Since this polynomial is of a degree 1.
There will be only one root.
