Question 410317: What formula should I use to find the answer to this problem: The base of a 22ft ladder is 8ft from a house. Approximately how far above the ground is the top of the ladder? I drew it and saw that it formed a triangle, but I am not sure if I am supposed to be finding the other side or when I do should I subtract it from 22.

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)
