Question

the sum of two angles of a triangle is equal to its angle . Determine the measure of third angle​

Answer 1

its a isosceles triangle.

2x+70 -180 .

angle sum property

Answer 2

Answer:

The two angles of the triangle are given as \[38^\circ\] and \[100^\circ\]. Since the sum of the angles of the triangles is equal to \[180^\circ\], the third angle is given by subtracting the sum of the other two angles from \[180^\circ\].
