*WILL MEDAL IF YOU CAN ANSWER!*
*TRIGONOMETRY*
In ΔABC, m∠B = 90°, cosC=11/17, and AB = 26 units.
Based on this information, m∠A=(33,40,50)°, m∠C=(33,40,50)°, and AC=(10,22,34) units.

Best ResponseYou've already chosen the best response.1ok using pythagorean theorem find AB the hypotenuse is the longest side of the right triangle so if given AB = 26 then you know AC is a multiple of 17 the factor will be same as 26 divided by what you calculated
