Answer:
Step-by-step explanation:
Given:
A shelf is built on a wall. The angles of the triangle are given as (x + 3)°, (2x - 18)° and 90°
We need to determine the value of x.
Value of x:
By triangle sum property, the angles in a triangle always add up to 180°
Thus, we have;
Simplifying, we get;
Subtracting both sides by 75, we get;
Dividing both sides of the equation by 3, we get;
Thus, the value of x is 35.

im sorry if its wrong
Answer:
D
Step-by-step explanation:
f(x) - g(x) = -9x^2 - 7x + 12 - (3x^2 - 4x - 15) Remove the brackets
f(x) - g(x) = -9x^2 - 7x + 12 - 3x^2 + 4x + 15
f(x) - g(x) = -9x^2 - 3x^2 - 7x + 4x + 12 + 15
f(x) - g(x) = -12x^2- 3x + 27
Answer D
15 i am pretty sure i’m probably gonna be wrong
