Another student has heard how smart you are and needs help finding the measure of 2 angles after being told only that Sine = Cos and that angle has (4x + 10) degrees and α β α that angle has (10x + 10) degrees. Please help him to find the measure of each angle and β add an explanation of the rules applied here and the steps taken so that this student can do this on their own next time.
Given triangle ABC whose sides AB=15 in, AC=25, BC=30. From point D on side AB, a line DE is drawn to point AC such that angle ADE is equal to angle ABC. If perimeter of ADE is 28 in, find the length of segments BD and CE
The tangent at any point on the eclipse x2/a2 +y2/b2 meets the tangents at the ends of the major axis Q and Q'. Show that the circle on QQ' has diameter passes through the foci.
BEL is a triangle. BE is 4 cm BL is 3.5 cm and angle LBE is 50°. Let M be a point on BL. Construct the imagine R of point B by the translation of vector v = vector EM. Construct the imagine F of point L by the translation of vector v. Calculate RF and angle FRM
