Ok so
-5x = 30
First divide both sides by -5 to get x by itself
You get: x = -6
Hope this helps!
<span><span>if one angle is x and the ratio of 1 : 4 : 7, means second angle is 4x and third angle is 7x
since the sum of all three angles in a triangle is 180 degrees, we have
x+4x+7x=180
12x = 180
x = 15
then
4x = 60
7x = 105
The angles are 15°,60 °, and 105 °.</span><span>
Therefore, yes.</span></span>
