 Question 410488: how does sin B = 0.6608 get transfromed into B = 41Degrees what step am i missing from changing 0.6608 to an angle (arrgggg) using law of sines when 33/SIN 57 degree = 26/ SIN B next step is 33sinB = 26sin57degree next step sin B = 26sin57degree/33 =0.6608 sin B = 0.6608 what do i do to get this then B = 41 degree (it all checks on a caulator) how do I get that SIN B = 0.6608 to = 41 degrees into an angle of a triangle how do you change that to this B = 41degree what am i missing (aaarrrrrggh) Click here to see answer by Theo(3458)
