In $$\triangle ABC, \angle B = 90$$. AD and CE are the medians drawn from A and C, respectively. If AC = 10 cm and $$AD = \sqrt{55}$$ cm, then the length of CE is:
The side BC of $$\triangle ABC$$ is produced to D. The bisectors of $$\angle ABC$$ and $$\angle ACD$$ meet at E. If AB = AC and $$\angle BEC = 35^\circ$$, then the measure of $$\angle ABC$$ will be:
A certain number of persons can complete a work in 54 days. If there were 15 persons less, it would take 18 days more for the work to be completed.Initially, the numberof persons is:
If $$a^2 + 4b^2 + 25 c^2 + 18 = 2(a - 2b + 20c), then what is the value of $$(a + 2b + 5c)$$?
A and B are two points on a circle with centre O. C is a point on the minor are ofthe circle between points A and B. The tangents to the circle at A and B meet each otherat a point D. If $$\angle ADB = 25^\circ$$, then $$\angle ACB$$ (in degrees)is equal to:
