Answer: the value of x is 15°
Step-by-step explanation:
A is 2x. B is 2(2x), so 4x. C is 3(2x) so 6x.
The sum of all the angles of a triangle is 180°
Set up the equation:
2x + 4x + 6x = 180
12x = 180°
x = 15°
Answer:
x=6,y=-11
Step-by-step explanation:
y=-3x+7
x=-2y-16
Substitute the second equation into the first every place you see an x
y=-3(-2y-16)+7
Distribute
y = 6y+48 +7
Combine like terms
y = 6y +55
Minus 6y from each side
y-6y = 6y-6y+55
-5y = 55
Divide by -5
-5y/-5 = 55/-5
y = -11
Now we need to find x
x=-2y-16
x = -2(-11) -16
x =22-16
x = 6
x=6, y= -11
Answer:
x = 3.431
Step-by-step explanation:
Given equation is,
By taking log on both the sides of the equation,
(3x - 9)log5 = log8
3x - 9 =
3x - 9 = 1.292
3x = 9 + 1.292
x =
x = 3.4306
x ≈ 3.431
