If you need to find an angle when three sides of an oblique triangle are known, use the law of cosines. The equation is: a2 = b2 + c2 - 2bc cos A Solve for A 2bc cos A = b2 + c2 - a2 cos A = (b2 + c2 - a2)/(2bc) A = cos-1[(b2 + c2 - a2)/(2bc)] A = cos-1[(142 + 152 - 132)/(2*14*15)] A = 53.13 Ok now here is my choices A. 53 Degrees 8' 48'' B 53 Degrees 8' 13'' C. 53 Degrees 7' 48'' D. 53 Degrees 7' 13'' How do I know which one it is? http://www.algebra.com/cgi-bin/jump-to-question.mpl?question=151014 This problem was solved by jojo14344: Andre,Kamwi and werner are truck drivers.

All radii of two or more circles are congruent. 2. Radii of the same circle are congruent. 3. The endpoint of the radius lies in the interior of the circle. 4. Diameters of the same circle are congruent. 5. The endpoints of any chord of any circle lies on the circle. 6. A diameter is a chord. 7. A chord is a diameter. 8. Twice the length of the diameter is equal to the length of the radius. 9. There exists a point x whose distance from the center of a circle is greater than the radius, so point x lies on the interior of the circle. 10. There exists a point y whose distance from the center of a circle is less than the radius, so point y lies on the interior of the circle. http://www.algebra.com/cgi-bin/jump-to-question.mpl?question=151195 This problem was solved by vleith: the graph of any equation of the form x = a constant yields a/an______________________line.
