The inclination of the line AB in the given figure is ___
30∘
45∘
60∘
90∘
We know x+2x = 90∘
3x=90∘
x=30∘
∴ the inclination = 2x
=(2×30∘)
=60∘
The inclination of the line 2y=2x+3 is
In the given figure, ∠AOB=90∘ and ∠ABC=30∘. Then, ∠CAO=?
(a) 30∘
(b) 45∘
(c) 60∘
(d) 90∘
In the given figure, AB is the diameter of the circle. AC is equal to BC. Find the value of ∠ABC.
