Answer:
x=54º
y=63º
Step-by-step explanation:
Let the other angle in the triangle be zº.
Because the measure of a line is 180º, zº=180º-117º=63º.
Because the triangle is isosceles yº=zº=63º.
The sum of the measure of the angles in a triangle is 180º. So, 63º+63º+xº=180º.
126º+xº=180º
xº=54º
Let's use the formula to find the perimeter of a rectangle.
2l+2w=120
We know that the length is twice its width; the equation would be:L=2w
We can plug that in to the formula.
2(2w)+2w=120
4w+2w=120
6w=120
120÷6=20=w
Since the length is twice its width, 20×2=40. The length is 40 cm.
The width is 20 cm.

Answer:
there is no answer to this
Step-by-step explanation:
4w-12=6w-36+14
4w-12=6w-22
10=2w
5=w
(I think)
The integers are x - 1, x and x + 1
x - 1 + x + x + 1 = 186
3x = 186
x = 186/3 = 62
Therefore, the numbers are 61, 62 and 63
