Answer:

Is a right triangle

Explanation:

step 1

Find the measure of angle C

Remember that

The sum of the internal angles of a triangle must be equal to 180 degrees

so

$m<A+m<B+m<C=180\°$

substitute the given values

$55\°+35\°+m<C=180\°$

$m<C=180\°-90\°=90\°$

therefore

The triangle is a right triangle, because has a internal angle of 90 degrees
