T = 60°
Step-by-step explanation:
Angle S = 180° - 150° = 30°
Angle U = 90°
Therefore, angle T is given by
S + U + T = 180
30° + 90° + T = 180°
or
Angle T = 60°
Answer:
it is 130 thats my answer

Answer:
The answer to your question is the letter D.
Step-by-step explanation:
Data
First rectangle Second rectangle
length = 3 length = 3
width = 2 width = 2 + 4 = 6
Process
1.- Calculate the Perimeter of the first rectangle
Perimeter = 2l + 2w
Perimeter = 2(3) + 2(2)
= 6 + 4
= 10
2.- Calculate the perimeter of the second rectangle
Perimeter = 2(3) + 2(6)
Perimeter = 6 + 12
Perimeter = 18
3.- Compare both perimeters
Perimeter 1 is smaller than Perimeter 2 by 8 units
Alright so you have $24 dollars. 1/6 of 24 is 4 so now you have $20 dollars left. 2/3 of 20 is 13.333. So you subtract 13.333 from 20 to get a final anwser of 6.6666666667 dollars that roger saved. Hope i could help.
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
A = x² + xy + 2y - 1 → (1)
A + B = 2x² - xy - 4y - 1 → (2)
From (2)
B = 2x² - xy - 4y - 1 - A
= 2x² - xy - 4y - 1 - (x² + xy + 2y - 1) ← distribute parenthesis
= 2x² - xy - 4y - 1 - x² - xy - 2y + 1 ← collect like terms
= x² - 2xy - 6y
Hence
A - B = x² + xy + 2y - 1 - (x² - 2xy - 6y) ← distribute parenthesis
= x² + xy + 2y - 1 - x² + 2xy + 6y ← collect like terms
= 3xy + 8y - 1
(b)
Given A - B = x, then
x = 3xy + 8y - 1 ( add 1 to both sides )
x + 1 = 3xy + 8y ← factor out y from each term
x + 1 = y(3x + 8) ← divide both sides by (3x + 8)
y =
