Question

How do you solve a right triangle when only given either one angle or one side ? Like my professor did not do a good job teaching this . Like i may have the 90 degree angle and another angle of 28 degrees . Then I may have side b which may be 7 and then the 90 degree angle . How do I solve this ?

Answer 1

if you know one angle and one side then to find 2nd side you can use trig.
to find 3rd angle use the fact all triangles add up to 180 degree

Answer 2

i know two angles 90+66
to find 3rd angle i can add both angles and then subtract it from 180 \[\rm 90+66+x=180 \] solve for x then u will get x=24
