Answer: 55°
Step by step:
80 + x = 180
x = 100
Because the bottom of the figure is a line which equals 180°, so you would subtract 80 from 180 to get the angle on the other side of the line dividing the triangles.
Then, you would use the triangle sum theory which states that the angles of a triangle equals to 180.
100 + 25 + x = 180
125 + x = 180
x = 55°
So angle CBD = 55°

➷ You could apply the difference of two squares rule
Square root 100 to get 10
The factored version would be:
(x + 10)(x - 10)
Test it out:
It will expand to x^2 + 10x - 10x - 100
As you can see, the '10x' will cancel out, leaving x^2 - 100 which suggests it is correct
