Question

The angle of a triangles are x°, (x + 25)° and (2x -9)°. What is the measure of the smallest angle?
a)39°
b)41°
c)67°
d)72°​

Answer 1

Answer:

The answer is 41 degrees

Step-by-step explanation:

As we know that addition of all angles of a triangle is always supplementary

And after adding and equating the equation the value comes like this -

x + x + 25 + 2x - 9 = 180 degrees

Add the like terms and equate

x + x + 2x + 25 - 9 = 180

4x + 16 = 180

4x = 180 - 16

4x = 164

x = 164/4

  = 41 degrees(option [b])
