thats liek grade 9 trig. just remember how to solve for "x", then you should be set. and study the radian wheel, pi/2=180 degrees etc.

use the law of sines.

sin11/26=sin90/x

once you find x, the hypotenuse, then use pythagorean theory to get the ofther side. and add up to 180 to find the other angle

( 26 x sin90 )/ sin11 = 136.262

thats it AB = 136.262

enjoy

buddy, here it is right here:

You know that the right angle is 90, and the other is 11. A triangle has 180 degrees inside, so 180-90-11 = 79. so angle C = 79.
Then Tan(-)=opp/adj, so tan79=opp/26...so find the tan of 79 and multiply it by 26. WHich gives you the opposite side, or AB.

(-) = theta.
