Answer:
m = 35°
Step-by-step explanation:
Supplementary angles, sum = 180°
m + 145° = 180°
m = 180° -145°
m = 35°

Answer:
The answer is C, zero solutions.
Step-by-step explanation:
y = 5/2x + 2
2y = 5x + 8
Multiply 2 to the first equation.
2y = 5x + 4
Compare it with the other equation
2y = 5x + 4
2y = 5x + 8
Cancel 2y and 5x on both sides.
Remaining:
4 = 8
4 ≠ 8. Therefore, the answer is C, zero solutions.
THE ANSWER TO THIS IS 3x-48
Answer:
9 units and 12 units to nearest hundredth.
Step-by-step explanation:
Let one leg be x units long then the other = x+3 units.
By Pythagoras:
x^2 + (x+3)^2 = 15^2 = 225
2x^2 + 6x + 9 = 225
2x^2 + 6x - 216 =0
x^2 + 3x - 108 = 0
(x - 9)(x + 12) = 0
x = 9
So the other 2 legs are 9 and 12.
