Answer:
its the 3rd choice.
Step-by-step explanation:
Firstly, we find angle BDC (180-90-30=60)
Now that we found it we can use the sine rule to find DB (which i put as an x), which is sin60/14=sin30/x, by cross multiplication, we find that its equal to a decimal number, i will use its root version to this easier, its equal to 14sqrt3/3 inches.
And now we use the pythagorean theorem to find DC, we find that it is equal to 28sqrt3/3
Now, we find angle BAC (180-90-(30+15)=45)
Again, we use the sine rule to find AB (whom i will refer to as x and from whom we will subtract DB to find the length of AD), so we cross multiply in sin45/14=sin(30+15)/x, it is equal to 14.
So since AB-DC=AD
14-(14sqrt3/3)= 5.917096231 (and we ound that to a 5.9)
Answer:
(m) + 2 (m) - 7 = 32 is the needed expression.
Points scored by Pittsburgh Steelers = 13
Points scored by New Orleans Saints = 19
Step-by-step explanation:
Let us assume the points scored by Pittsburgh Steelers = m
So, the Points scored by New Orleans Saints
= 2 (Points scored by Pittsburgh Steelers ) - 7
= 2 (m) - 7
Also,the total points scored by both teams = 32
So the points scored by( New Orleans Saints + Pittsburgh Steelers) = 32
⇒ (m) + 2 (m) - 7 = 32
or, 3 m = 32 + 7 = 39
⇒ m = 39/ 3 = 13, or m = 13
So, the points cored by Pittsburgh Steelers = m = 13
and the points scored by New Orleans Saints = 2m - 17
= 2(13) - 7 = 19
All I did was add all A's, B's, and C's separately. Than I added them all together and got 316 total surface area. I tried but I learned this sooo long ago so i'm sorry if you get it wrong. Good Luck!
