OK.....you do not seem to be learning any of this material.....many of your many questions are very similar and require similar thinking and formulas.....TRY to get an answer THEN ask for help.....
Triangle area = 1/2 base * height You SHOULD be able to answer the question with this bit of info....TRY! You learn NOTHING by only looking for answers!
5. All three angles of a triangle total to 180 degrees....
you are givern two of them and need the third ('x') sooooo 180 = x + 61 + 32 Find 'x'
6. This can be set up as a ratio you need to find 't'
5 ft 6in = 66 in 2 ft = 24 in 1.5 ft = 18 in (best to be consistent with units)
66in/24in = t/18 in Find 't' (which will be in inches)
