Answer:
x = 7
Step-by-step explanation:
=> 7x+9 = 8x+2 (Corresponding angles are equal)
=> 8x-7x+2 = 9 (Subtracting 7x to both sides)
=> x = 9-2 (Subtracting 2 to both sides)
=> x = 7
The largest angle is 5/9 of the total which in a triangle is 180 degrees
5/9 x 180 = 100 degrees
Answer:
Step-by-step explanation:
Answer:
(x, y) = (-1, 6)
Step-by-step explanation:
y = 2x + 8
y = 5 - x
Substituting the second equation into the first equation, we get:
5 - x = 2x + 8
5 = 3x + 8
-3 = 3x
x = -1.
So, y = 5 - (-1).
Simplifying, we get:
y = 6.
