The angles should measure 180º.

<span>5° + 75°+ 100° = 180°

</span><span>10°+ 80°+ 90° = 180°
</span>
20° + 60° + 100° = 180°

45° + 45° + 45° = 135°

50° + 50° +  80° = 180°

So D does not represent interior angle measures of a triangle.

Hope this Helps!!

A rectangle's length is twice its width. if the perimeter is 120 cm, find the width of the rectangle.
dangina [55]
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.
