In triangle def = 18 and m angle f = 45. find the length of a leg rounded to the to the nearest tenth.

Hello there!

If DEF = 18, we then use the sin method, or the law of sin.

18 divide by sin90 would be F = sin45 .

We therefore end up with 12.72 but rounded would be 12.7 as 2 is lower than 5, so, it just rounds back down to 7.

Your 12.7

b) well because you get well

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
