M 2 = 2x°, m 3 = 5x°, m 1 =<br><br> 2x + 5x<br> 5x - 2x<br> 180 - 5x<br> 180 - 7x

MaRussiya [10]

We know: the sum of measures of triangle angles is 180°.

Therefore we have the equation

$m\angle1+m\angle2+m\angle3=180^o\to m\angle1=180^o-m\angle2-m\angle3$

Substitute $m\angle2=2x,\ m\angle3=5x$ :

$m\angle1=180-2x-5x=180-7x$

<h3>Answer: 180 - 7x</h3>

Which term describes the point where the perpendicular bisectors of the three sides of a triangle intersect

MissTica

Given statement is "point where the perpendicular bisectors of the three sides of a triangle intersect".

Perpendicular is basically a vertical line that makes 90 degree angle with the base.

bisector means the line which divides side into two equal parts.

So perpendicular bisector in any triangle will be the line which is drawn on the side of the triangle and perpendicular to that side.

Now these perpendicular bisectors meet at some point.

That point is called circumcenter.

Hence final answer will be "circumcenter".
