Who discovered the virus?
Dmitry Ivanovsky was a pioneer in the discovery of viruses, having conducted foundational research that led to the identification of these infectious agents.
In a ∆ABC, points P, Q and R are taken on AB, BC and CA, respectively, such that BQ = PQ and QC = QR. If ∠ BAC = 75°, what is the measure of &...
A △ ABC has sides 5 cm, 6 cm and 7 cm. AB extended touches a circle at P and AC extended touches the same circle at Q. Find the length (in cm) of AQ.
If in triangle ABC, If side AB=6√ 3, AC=12 and BC=6, then angle B equals:
