An angle whose measure is greater than 90°, but less than 180° is called an obtuse angle
A cuboidal water tank contains. 216 l of water. Its depth is ⅓ of its length and its breadth is ½ of ⅓ of the difference between length and depth. The length of the tank is: 18dm
step by step explanation:
If cosθ>0 and tanθ<0, then the terminal arm of the angle 𝜃 lies in the fourth quadrant.
In the fourth quadrant, cosine is positive, and tangent is negative.
For an angle in the first quadrant the point P has positive x and y coordinates.
Therefore: In Quadrant I, cos(θ) > 0, sin(θ) > 0 and tan(θ) > 0 (All positive).
Area of the square = 49cm²
Side of square = X
Area of the square = X²
49= X²
X² =49
X=√49
X= 7
The side of the square =X=7cm
= log36 / log 6
= 1.556 / 0.778
= 3

If a line intersects two coplanar lines, then the two internal angles on the coplanar lines are called corresponding angles.
