Question
In May 2023, which Indian scientist at the Exoplanet
Research Group of the Physical Research Laboratory (PRL), Ahmedabad led the international team which discovered a new Jupiter-size exoplanet with the highest density known till this date and mass 13 times than that of Jupiter?Solution
The correct answer is A
Find the length of AB, if ΔABC ~ ΔRQP and BC = 14 cm, QP = 7 cm and RQ = 5 cm.
Calculate the hypotenuse of an isosceles right-angled triangle where the equal sides are 8√6 cm each.
What is the length of the hypotenuse in an isosceles right-angled triangle if one of its equal sides measures 5√3 cm?
If in triangle ABC, If side AB=6√ 3, AC=12 and BC=6, then angle B equals:
In triangle ABC, DE is drawn parallel to BC, meeting AB at D and AC at E. If AD : DB = 3 : 2 and the area of triangle ADE is 45 cm², find:
(a) t...
In a right-angled triangle, the two perpendicular sides are 9 cm and 12 cm. What is the radius of the incircle of the triangle?
- In triangle XYZ, UV is drawn parallel to side YZ. If XU = 10 cm, UX = 6 cm, and XV = 15 cm, find XZ.
Find the length of AB, if ΔABC ~ ΔRQP and AC = 22.5 cm, RP = 9 cm and RQ = 6 cm.
Two triangles DEF and XYZ are similar to each other. If DE = 5 cm, DF = 7 cm, and XY = 15 cm, then find XZ.
If the side of an equilateral triangle is 12cm, then find the area (in cm 2 ) of the triangle (correct to two decimal places).
