Answer:
Step-by-step explanation:
(3x + 2) + (x - 4) = 90
4x - 2 = 90
4x = 92
x = 23
m∠A = (3(23) + 2) = 71°
After graphing the lines, you can see that the solution is (4, -1)
Answer:
Step-by-step explanation:
-5x + 10 > -15 is your original equation.
You need to isolate the x variable.
Start by subtracting 10.
-5x > -25
x > 5
Answer:
b = 20, c = 160
Step-by-step explanation:
b and 20 degrees are vertical angles, so they are equal.
b (20 degrees) and c are on a line together, so they add up to 180. 180 - 20 = 160 degrees
