Answer:
36
Step-by-step explanation:
ƒ(x) = 5x^2 − 9x + 18,
Let x=3
ƒ(3) = 5*3^2 − 9*3 + 18,
=5*9 - 27+18
45 - 27+18
36
Answer:
( -
/2 , -1/2)
Step-by-step explanation:
-210 degrees in standard position corresponds to an angle in the 3rd quadrant 30 degrees below the negative x-axis
The hypotenuse of the triangle here is 1, and we want the coordinates.
_______________________(0,0)
|(x = -root(3)/2)
|
| (y = -1/2)
The value of x is 36.
Solution:
Given angles of a triangle are 2x°, 2x° and x°.
To find the value of x:
<em>Sum of the all the angles of a triangle = 180°</em>
2x° + 2x° + x° = 180°
5x° = 180°
Divide by 5 on both sides of the equation.
x° = 36°
x = 36
The value of x is 36.
I needa see it tho for I could help
