Answer:
<h2>The obtuse angle is 120°.</h2><h2>The acute angle is 60°.</h2>Step-by-step explanation:
This problem is about two crossing line, when that happens, we have 4 angles, two acute and two obtuse, where adjacent angles are supplementary and vertical angles are equal.
We can form the expression
Where is an acute angle and
is an obtuse angle.}
Using all the given information, we have
Solving for , we have
Therefore, the obtuse angle is 120°, which means the acute angle is 60°, because they are supplementary angles, as we said befor.
