Answer:
76˚
Step-by-step explanation:
All angles of a triangle total up to 180˚ so we can make this equation:
x - 14 + 1/2x + 7 + 2x - 128 = 180
3.5x - 135 = 180
3.5x = 315
x = 90
Angle A is x - 14
90 - 14
76
4 is the slope and -1 is the y-intercept
Answer:
k = 2
Step-by-step explanation:
Fill in the given point values and solve for k.
y = (1/2)x + k
1 = (1/2)(-2) +k . . . . . . for x = -2, y = 1
1 = -1 +k . . . . simplify; next, add 1
2 = k
