Answer: x = 20
Step-by-step explanation:
Multiply by 10 ( next LCF )
10 ( x / 2 + 2x / 5 ) = 18 * 10
5x + 4x = 180
9x = 180
x = 20
The value of x is 60, as you wrote. The sum of all angles in a triangle is 180°.
The sum of all angles on a straight line is also 180°. So to find y, solve for the third angle of the triangle on the left.
50 + 60 = 110. 180-110 = 70°.
Now we know 2 of the 3 angles along the line (70° and x, 60°)
70 + 60 + y = 180
130 + y = 180
y = 50

Answer: 4
Step-by-step explanation: 1/4w + 1/4w + w + w = 10
2/4w + 2w = 10
1/2w + 2w = 10
2.5w = 10
Divide 10 by 2.5
width = 4
