Answer:
= 150°
Step-by-step explanation:
Since the polygons are regular, certain mathematical assumptions would help us here.
A square is a quadrilateral with all it's 4 sides equal and all it's angles equal.
Sum of angles of a regular quadrilateral = 360.
Therefore, a single angle = 360/4
= 90°.
The Triangle is adjacent to the side of the square. We will thus assume it's an Equilateral triangle.
For an equilateral triangle, all it's 3 angles = 180.
A single angle = 180/3
= 60°.
With this,
Angle ABC = 90° + 60=
= 150°

To write an equation in standard form, move each term to the right side of the equation and simplify.
y=ax^2 + bx + c
y=ax^2+bx+c
Solve for
y
Simplify each term.
y=x^2−8x+16+22
Add 16 and 22 to get 38.
y=x^2−8x+38
Answer:
949
Step-by-step explanation:
If the 3 digit number is rounded to 900, then this number is between 900 and 950.
The digit in the ones place is the fifth odd number begginning with 1, so this number is number 9.
Lastly, the sum of digits is 22.
Putting our number as 9x9, where x is the tens digit, we know that 9 + x + 9 = 22, so we have that x = 4
So, our number is 949
