Arthur Holmes proposed the Convection Current Theory, explaining mantle dynamics caused by thermal differences due to radioactive decay. These convection currents are pivotal to understanding processes such as plate tectonics and seafloor spreading.
MN is a diameter of a circle with centre O. The tangent at 'P' meets MN produced at 'Q'. If ∠PMN = 44 ° , then find ∠PNQ.
AB is parallel to DC in a trapezium ABCD. It is given that AB > DC and the diagonals AC and BD intersect at O. If AO=3x-15, OB = x +9, OC =x-5 and OD = ...
In the given Figure, Find angle BCD. If AB is a diameter & AB is parallel to CD.
In a triangle ABC, AB = 13 cm, BC = 14 cm, and AC = 15 cm. Find the area of the triangle and the length of the altitude from vertex A to side BC.
The length of the diagonal of a rectangle is 25 cm, and the ratio of its length to its breadth is 4:3. Find the area of the rectangle.
If O is circumcentre of acute angled triangle ABC, if ∠OBC = 150 then ∠BAC = ?
If in a ΔABC, AD is internal angle bisector & D is a point on BC, AB = 6cm, BC = 9cm then what is BD:CD?
In ∆ABC, AB = 5cm, BC = 10cm, and AC = 13cm then find out the value of cos A.
∆ ABC is similar to ∆ DEF. If area of ∆ABC is 9 sq.cm and area of ∆DEF is 16 sq.cm and BC = 2.1 cm. Then the length of EF will be
A triangular field has sides 13 m, 14 m, and 15 m. A well with a diameter of 7 m is dug outside the field. If the entire soil dug from the well is used ...
