The two corners of the triangle are 147 and 27 find the obtuse angle.

As we know, the sum of all the angles of any triangle is 180 °. In the task, we need to find an unknown third angle, which must be obtuse, that is, it must be less than a right angle and must be less than 90 °.

To find the unknown angle, we first find the sum of the two known angles. To do this, add:

147 ° + 27 ° = 174 ° is the sum of 2 known angles.

To find what the third angle is equal to, you need to subtract the sum of two angles from the sum of three angles:

180 ° – 174 ° = 6 °.

3 the angle is really obtuse, since 6 ° <90 °.

Answer: 6 °.
