Answer:
x = 1
Step-by-step explanation:
If y = -3...
y = 7x - 10
-3 = 7x - 10
10 + -3 = 7x - 10 +10
7 = 7x
(1/7) 7 = 7x (1/7)
1 = x
Answer:
-3,0
Step-by-step explanation:
Answer:
72° is the largest angle, 63°, 45°
Step-by-step explanation:
7x + 5x + 8x = 180
20x = 180
20x/20 = 180/20
x = 9
I set the equation equal to 180 because there are 180 degrees in a triangle.
Now find the largest angle, which will be the 8x, since 8 is bigger than 5 and 7.
8x
8(9)
72° is the largest angle
If you need the other two angle measures:
7x
7(9)
63°
5x
5(9)
45°
I think it could be B because it is not a 90 and it too small for an 82 but too big for a 44 and 126 is too open.
