Answer:
7.5 = OM
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opposite side / hypotenuse
sin 30 = OM / UN
sin 30 = OM / 15
15 sin 30 = OM
7.5 = OM

Answer:
D = 0
Step-by-step explanation:
Given
x-intercept = -3
Required
What does the discriminant represent?
The discriminant of a quadratic function can take any 3 values; these are as follows;
- When D > 0
- When D < 0
- When D = 0
Which translates to
- signifies that two different real roots exist
- signifies that only complex roots exist
- signifies that the two identical real roots exist
The question says that x-intercept = -3 is the only value;
This means that: x = -3 or x = -3
Analyzing the roots
- 3 and -3 are identical
- -3 and -3 are real
This means they satisfy condition number 3;
Hence, D = 0
Bisector => AD = CD => 3y+6 = 5y-18 => 2y = 24
=> y=12
