Answer:tbh, that's impossible
Step-by-step explanation:
Answer:
y = 20°
x = 35°
Explanation:
Equation's:
1) 2y + x + 105° = 180°
2) 3x + x + 2y = 180°
Make y subject in equation 2
3x + x + 2y = 180
4x + 2y = 180
2y = 180 - 4x
y = 90 - 2x
Insert this into equation 1
2(90 - 2x) + x + 105° = 180°
180 - 4x + x + 105 = 180
-3x = -105
x = 35°
Find value of y
y = 90 - 2x
y = 90 - 2(35)
y = 20°
Answer:
5
Step-by-step explanation:
move the terms 6x-4=16+2x
collect like terms 6x-2x=16+4
divide both sides 4x=20
x=5
Answer: Angle BEC is also 45 degrees.
Step-by-step explanation: This is because the opposite and congruent angle of BEC is 45 degrees. Congruent means the same. Therefore, Angle BEC is 45 degrees.
Answer:
rate change: -8
Equation: y = 232 -8x
After 5 hours: 192
Step-by-step explanation:
8 are destroyed every hour, so there are 8 less every hour, so the rate of change is -8
It starts with 232 and loses 8 per hour, so the formula is
y = 232 - 8x
After 5 hours:
y = 232 - 8(5)
y = 232 - 40
y = 192
