Answer:
12
Step-by-step explanation:
The sum of any two sides of a triangle must be greater than the third side.
Since line t is a transversal line all angle which are perpendicular with 63 will equal to the same value (63) and also line m is a straight line where it’s total will be 180
So,
3x + 2x + 63 = 180
5x + 63 = 180
5x = 180 - 63
5x = 117
Divide by 5 throughout
X = 23.4degrees
Answer:
A= 8
B= -5
C= -14
Step-by-step explanation:
Area of Rectangle = length * width
Area of the shaded Rectangle:
Area = l * w
Area= (4x + 1) (3x - 5)
Open the brackets
A= 12x^2 - 20x + 3x - 5
A = 12x^2 - 17x - 5
Area of the Unshaded:
The Unshaded portion is a square. Hence, it's area = l^ 2
Area = (2x - 3) ( 2x - 3)
A= 4x^2 - 6x - 6x + 9
A= 4x^2 - 12x + 9
To get the exact shaded portion
A(Shaded) = (12x^2 - 17x - 5) - ( 4x^2 - 12x + 9)
Area = 8x^2 - 5x - 14
A= 8
B= -5
C= -14
Factored, the trinomial equals (x+5)(x+5) or (x+5)^2
