Question

5. The sum of the angles of a triangle is 180°. If the three angles of a triangle are (2x +15)0,85° and (x + 20°, find
the value of x​

Answer 1

Since the sum is 180°.

2x+150+85+x+20=180°

3x+255=180°

3x=180-255

3x=-65°

x=-21.66°

Since the angle is negative therefore such triangle doesn't exist.
