In triangle DEF = 18 and m angle F = 45. Find the length of a leg rounded to the to the nearest tenth.
1 answer:
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 answer: 12.7

Answer:
True
Step-by-step explanation:
3.14 x 9^2 x 14/3 = 1186.92
4/3 x 3.14 x 9^3 = 1526.04
1186.92 + 1526.04 = 2712.96 = 2713 cubic inches
